Description

Resource allocation method, communication device and communication equipment

Technical Field

The present application relates to the field of communications, and in particular, to a resource allocation method, a communication apparatus, and a communication device.

Background

In a mobile communication system, a Physical Uplink Control Channel (PUCCH) resource is used to carry Uplink Control Information (UCI), for example, the UCI may include hybrid automatic repeat request (HARQ), channel State Information (CSI), or Scheduling Request (SR).

The network device may configure a dedicated symbol region of the PUCCH resource for the terminal device, and if the number of configured symbols in the dedicated symbol region of the PUCCH is too many, resource waste will be caused. If the number of configured symbols in the PUCCH symbol region is too small, UCI cannot be transmitted in time. The current PUCCH resource configuration mode has the problem of low resource utilization rate.

Disclosure of Invention

The application provides a resource allocation method, a communication device and communication equipment, which can improve the resource utilization rate.

In a first aspect, a resource allocation method is provided, which may be performed by a network device or a module (e.g., a chip) configured on the network device.

According to the above scheme, the network device may schedule part of the configured PUCCH resources for data transmission according to the requirement, and accordingly, the terminal device will transmit data on the scheduled resources in response to the scheduling of the network device, for example, when the network device schedules the PUCCH resources to transmit UCI, the terminal device transmits UCI on the scheduled PUCCH resources, and if the network device schedules the PUSCH resources to transmit data, and the PUSCH resources include part of the PUCCH resources, the terminal device still transmits data on the scheduled resources based on the scheduling. Therefore, the network equipment can schedule part of resources of the PUCCH resources to transmit data when the UCI transmission requirement is small or the data transmission requirement is large, and the resource utilization rate and the uplink transmission rate can be improved. On the other hand, the network device does not need to reconfigure the PUCCH resource for the terminal device through RRC signaling, and the terminal device only needs to respond to the scheduling of the network device to perform uplink data transmission or UCI transmission. The terminal equipment and the network equipment can achieve consensus, signaling overhead can be reduced, and resource utilization rate is further improved.

With reference to the first aspect, in certain implementations of the first aspect, the method further includes: determining one or more first uplink control channel resources in the plurality of uplink control channel resources according to a first resource demand degree, wherein the first resource demand degree is the demand degree of the uplink resources within a first time range; and transmitting second information in a second time range, wherein the second information is used for scheduling uplink control channel resources in the one or more first uplink control channel resources, the first information is transmitted in the second time range, and the first uplink shared channel resource comprises resources except the first uplink control channel resource in the plurality of uplink control channel resources.

The network device and the terminal device can communicate by adopting the resource allocation method provided by the embodiment of the application.

The terminal device in the embodiments of the present application may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device in the embodiment of the present application may be a mobile phone, a tablet computer, a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation security, a wireless terminal in a smart city, a wireless terminal in a smart home, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a wireless communication function, a computing device, a vehicle-mounted device, a wearable device, a terminal device in a 5G network, or a device in a public land mobile communication network (PLMN) terminal in future evolution. It should be understood that the present application is not limited to the particular form of the terminal device.

The network device in the embodiment of the present application may be a device having a wireless transceiving function in an access network. Such devices include, but are not limited to: a base station, an evolved node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved node B, or home node B, HNB), a Base Band Unit (BBU), an Access Point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a Transmission Point (TP), or a Transmission and Reception Point (TRP), etc. The device may also be a network node forming a gNB or a transmission point, such as a baseband unit (BBU), or a Distributed Unit (DU), etc. It should be understood that the present application is not limited to the particular form of network device.

The network device may configure one or more PUCCH resource sets for the terminal device through Radio Resource Control (RRC) signaling, where each PUCCH resource set includes one or more PUCCH resources. Each PUCCH resource employs one of 5 PUCCH formats (PUCCH formats), format 0 to format 4, shown in table 1. Each PUCCH format corresponds to a time domain length range (represented by a value range of the number of OFDM symbols) of a PUCCH resource and a bit number range that can be carried by the PUCCH resource. And when the network equipment configures the PUCCH resource set, indicating the number of OFDM symbols occupied by the time domain of each PUCCH resource. For example, if the PUCCH resource set configured by the network device for the terminal device includes a PUCCH resource of PUCCH format 0, the network device may specify that the PUCCH resource of PUCCH format 0 occupies 1 OFDM symbol or 2 OFDM symbols in the configuration information. And when the terminal equipment transmits the UCI on the PUCCH resource, the length of the transmitted UCI is not more than 2 bits.

TABLE 1

PUCCH format	Length (OFDM symbol number)	Number of bits
			0	1-2	≤2
1	4-14	≤2
			2	1-2	>2
3	4-14	>2
			4	4-14	>2

The set of OFDM symbols occupied by one or more PUCCH resources configured by the network device for the terminal device may be referred to as a PUCCH-dedicated symbol region, and resources in the PUCCH-dedicated symbol region are only used for carrying UCI. The terminal device transmits UCI on a PUCCH resource of the one or more PUCCH resource sets before the network device reconfigures (or is otherwise referred to as updating) the PUCCH resource set for the terminal device. The network device needs to update the PUCCH symbol region through RRC reconfiguration, and notify the terminal device of the updated symbol region and the PUCCH resource therein. However, the time interval of RRC reconfiguration is long, and before the network device reconfigures the PUCCH symbol region for the terminal device, if the number of symbols in the PUCCH symbol region configured by the network device is too large, resource waste will be caused. And the uplink resource is limited, when the number of symbols in the PUCCH symbol region is too many, the Physical Uplink Shared Channel (PUSCH) resource for transmitting data will be reduced, and the transmission rate of the uplink data is reduced. If the number of symbols in the PUCCH symbol region is too small, UCI cannot be transmitted in time when UCI transmission requirements cannot be met. According to the method and the device, the network equipment can schedule part of configured PUCCH resources for data transmission according to requirements, the terminal equipment transmits uplink data on the scheduled resources based on the scheduling of the network equipment, if the network equipment schedules the PUCCH resources for UCI transmission, the terminal equipment transmits the UCI on the scheduled PUCCH resources, and if the network equipment schedules the PUSCH resources for data transmission and the PUSCH resources contain part of the configured PUCCH resources, the terminal equipment still transmits the data on the corresponding resources based on the scheduling of the network equipment. Therefore, the network equipment can schedule PUCCH resources to transmit data when UCI transmission requirements are small or data transmission requirements are large, and resource utilization rate and uplink transmission rate can be improved. On the other hand, the network device does not need to reconfigure the PUCCH resource for the terminal device through RRC signaling, and the terminal device only needs to respond to the scheduling of the network device to perform uplink information transmission. The terminal equipment and the network equipment can achieve consensus, signaling overhead can be reduced, and resource utilization rate is further improved.

The following describes a resource allocation method provided in an embodiment of the present application with reference to the drawings.

Fig. 2 is a schematic flow chart of a resource allocation method 200 according to an embodiment of the present application. In the following, uplink control channel resources are taken as PUCCH in the mobile communication system, and uplink control information is taken as UCI in the mobile communication system as an example for description, which should be understood that the present invention is not limited thereto. The scheme provided by the application can also be applied to other communication systems.

S210, the network device sends configuration information, where the configuration information is used to configure multiple PUCCH resources.

The network device configures a plurality of PUCCH resources, and the network device can inform one or more terminal devices of the PUCCH resources configured by the network device for each terminal device through one or more pieces of configuration information. The one or more terminal devices may be terminal devices that establish a communication connection with the network device.

Accordingly, the terminal device receives configuration information from the network device. After the terminal device receives the configuration information, the PUCCH resource configured for the terminal device by the network device may be determined according to the configuration information.

The plurality of PUCCH resources occupy different time domain resources and/or frequency domain resources. The network device may be configured to select, from the plurality of PUCCH resources, a PUCCH resource actually used for carrying UCI for a period of time according to a transmission requirement, so as to improve resource utilization.

It should be noted that the plurality of PUCCH resources are PUCCH resources in one uplink time unit, and the plurality of PUCCH resources are applicable to each uplink time unit. By way of example and not limitation, the uplink time unit may be a maximum time granularity of uplink scheduling of the network device, such as an OFDM symbol group, a sub-slot (mini-slot), a slot (slot), a subframe (subframe), or a frame (frame).

S220, the network device sends first information to the terminal device, where the first information is used to schedule a first PUSCH resource, and the first PUSCH resource includes a partial resource in the plurality of PUCCH resources.

Accordingly, the terminal device receives the first information from the network device, and may determine to transmit uplink data on the first PUSCH resource according to the first information.

The network device may schedule a part of resources included in the plurality of PUSCH resources to transmit data according to the transmission requirement.

Optionally, the network device may determine one or more first PUCCH resources from the multiple PUCCH resources configured by the network device according to the first resource requirement. The first resource demand degree is the demand degree of uplink resources in a first time range, and the one or more first PUCCH resources are used as alternative PUCCH resources for carrying UCI in a second time range. The second time range is subsequent to the first time range. Each time range (e.g., first time range, second time range) includes at least one uplink time unit.

In a second time range, the network device selects a PUCCH resource for carrying UCI among the one or more first PUCCH resources. For example, the network device may transmit second information in the second time range, the second information being used to schedule one of the one or more first PUCCH resources. Accordingly, the terminal device receives the second information from the network device and transmits UCI on the first PUCCH resource scheduled by the second information.

In a second time range, the network device will not schedule the configured resources except the first PUCCH resource in the second time range to carry UCI. That is, resources other than the first PUCCH resource among the plurality of PUCCH resources are not used to carry UCI in the second time range, and may be scheduled by the network device to carry uplink data as PUSCH resources.

The first information may be transmitted in the second time range, and the first PUCCH resource may include a resource other than the first PUCCH resource among the plurality of PUCCH resources. According to the scheme, resource waste can be reduced, and the resource utilization rate and the uplink transmission rate can be improved.

Optionally, the network device may periodically determine, with a first time range as a period, an alternative PUCCH resource for carrying UCI in a next period, where a duration of the first time range is equal to a duration of a second time range, and the second time range is the next period of the first time range.

The following describes an optional embodiment in which the network device determines one or more first PUCCH resources from the configured plurality of PUCCH resources according to the first resource requirement in the first time range.

Optionally, the plurality of PUCCH resources occupy a first resource set, where the first resource set includes one or more resource units, the resource units are time domain resources and/or frequency domain resources, and the one or more first PUCCH resources are PUCCH resources belonging to a second resource set among the configured plurality of PUCCH resources, where the second resource set is a subset of the first resource set.

In one embodiment, the resource unit is a time domain resource.

For example, the resource elements may be time domain symbols. Symbols occupied by the plurality of PUCCH resources configured by the network device in the time domain constitute a first symbol set, the network device determines a second symbol set in the first symbol set according to a resource requirement degree (i.e., a first resource requirement degree) of uplink resources in a first time range, the second symbol set includes at least one PUCCH resource in the plurality of configured PUCCH resources, and the network device uses the PUCCH resource included in the second symbol set as an alternative PUCCH resource in a second time range, i.e., the first PUCCH resource.

For example, the network device may configure 8 PUCCH resources, where the 8 PUCCH resources occupy the last 4 Orthogonal Frequency Division Multiplexing (OFDM) symbols in one uplink time unit in the time domain.

The 8 PUCCH resources may be, as shown in fig. 3, the 8 PUCCH resources configured by the network device for the terminal device are PUCCH resources 0 to 7 (denoted as Ri, i =0, \8230;, 7, for example, PUCCH resource 0 is denoted as R0), the 8 PUCCH resources occupy the last 4 OFDM symbols (i.e., symbol 10 to symbol 13) in the 14 symbols (i.e., symbol 0 to symbol 13) of one uplink time unit in the time domain, and then the last 4 OFDM symbols are the first symbol set. The network device determines the alternative PUCCH resources in the second time range according to the first resource demand degree in the first time range, for example, the network device may determine, based on the first uplink resource demand degree, symbols that are occupied by the alternative PUCCH resources in the second time range are reduced. For example, the candidate PUCCH resources in the first time range are the 8 PUCCH resources configured by the network device, the network device may reduce symbols occupied by 1 PUCCH resource, and use symbols 11 to 13 as a second symbol set, where the second symbol set includes 6 PUCCH resources from R2 to R7, and then the 6 PUCCH resources are the first PUCCH resources, that is, the candidate PUCCH resources in the second time range. The network device schedules a PUCCH resource of the 6 PUCCH resources to carry UCI in a second time range, without scheduling R0 and R1 to carry UCI. In addition, the symbol 10 may be scheduled to transmit data according to a requirement in the second time range, which may reduce unnecessary PUCCH resource overhead in the second time range, and may increase available resources for transmitting data, thereby increasing an uplink data transmission rate.

The 8 PUCCH resources may also be as shown in fig. 4, where one or more of time domain positions, frequency domain positions, or resource sizes of the 8 PUCCH resources (e.g., R0 to R7 in fig. 4) allocated by the network device to the terminal device may be different, for example, R0 occupies 4 symbols in the time domain, R3 and R6 occupy 3 symbols in the time domain, R4 and R5 occupy 2 symbols in the time domain, and R2 and R7 occupy 1 symbol in the time domain. The size of the frequency domain resource occupied by R0 is larger than the size of the frequency domain resource occupied by other PUCCH resources. The 8 PUCCH resources may partially overlap with each other, such as R2 and R3. One PUCCH resource may also contain another PUCCH resource, such as R0 and R1. This is not limited in this application. The network device may determine that the second symbol set includes symbol 12 and symbol 13 according to the first resource requirement degree in the first time range, and symbol 12 and symbol 13 contain 4 PUCCH resources, which are R1, R2, R5, and R7, and then the 4 PUCCH resources are alternative PUCCH resources in the second time range. The network device schedules a PUCCH resource of the 4 PUCCH resources to carry UCI in a second time range, and PUCCH resources other than the 4 PUCCH resources of the 8 PUCCH resources are not used for carrying UCI in the second time range. The available resources for transmitting data can be increased, and the uplink data transmission rate can be improved.

Optionally, the network device may specifically determine, according to the first resource requirement and a corresponding relationship, a first number of resource units corresponding to the first resource requirement, where the corresponding relationship includes a corresponding relationship between a plurality of resource requirements and a plurality of numbers of resource units, and the plurality of resource requirements includes the first resource requirement. The network device determines a second set of resources in the first set of resources according to the first number, the second set of symbols including the first number of resource elements.

In this embodiment, if the resource unit is a time domain resource, for example, the resource unit is a time domain symbol, the first number is a first symbol number corresponding to the first resource requirement degree, and the corresponding relationship includes a corresponding relationship between a plurality of resource requirement degrees and a plurality of symbol numbers. The network device determines a second symbol set in the first symbol set according to the first symbol number, wherein the second symbol set comprises the symbols of the first symbol number.

For example, a plurality of value ranges of the uplink resource demand degree P correspond to a plurality of symbol numbers, the corresponding relationship may be as shown in table 2, and 3 value ranges of the uplink resource demand degree P correspond to 3 symbol numbers, for example, if the network device determines that the first uplink resource demand degree in the first time range is P1, if P1 is less than A1, the network device may determine that the second symbol set includes M1 symbols. Alternatively, the network device may determine the specific positions of the M1 symbols in the first symbol set according to a preset rule, for example, the preset rule may provide that after the number of symbols is determined, the symbols of the last consecutive corresponding number of symbols in the first symbol set are selected. The network device may determine that the second symbol set includes the last M1 symbols in the first symbol set, and then determine at least one PUCCH resource included in the last M1 symbols in the first symbol set, where the at least one PUCCH resource is an alternative PUCCH resource (or an available PUCCH resource) in the second time range. As shown in fig. 3 or fig. 4, selecting the last consecutive symbol when determining the second symbol set may cause the unselected symbols in the first symbol set to form consecutive resources with symbol resources other than the first symbol set in the time unit for carrying data. But the application is not limited thereto. The symbols in the second set of symbols may also be non-contiguous or M1 symbols starting at a starting time in the first set of symbols.

TABLE 2

Degree of resource requirement P	Number of symbols
		P＜A1	M1
A1≤P＜A2	M2
		A2≤P	M3

It should be noted that, when configuring the PUCCH resources, the network device needs to configure at least one PUCCH resource in each possible second resource set, for example, the network device may configure at least one PUCCH resource in the second symbol set corresponding to each possible symbol number according to the corresponding relationship.

For another example, the correspondence relationship may be as shown in table 3, and the number of symbols included in the second symbol set may be determined based on the first uplink resource demand P1 in the first time range and the number of symbols M occupied by the candidate resources of the PUCCH resource in the first time range. For example, the alternative PUCCH resource for carrying UCI in the first time range is at least one second PUCCH resource of the configured plurality of PUCCH resources, and the symbol set occupied by the at least one second PUCCH resource is a third symbol set, where the third symbol set includes M symbols. If P1 is less than A1, the network device may determine, according to the correspondence shown in table 3, that the number of symbols included in the second symbol set needs to be reduced by 1 symbol compared with the number of symbols M included in the third symbol set, and it needs to be ensured that at least one symbol of the PUCCH resource included in the uplink time unit in the second time range can transmit UCI, so that the number of symbols included in the second symbol set may be the maximum value of M-1 and 1, that is, max (M-1, 1). If A1 is less than or equal to P1 and less than A2, the network device may determine that the number of symbols included in the alternative PUCCH symbol set in the second time range may remain unchanged, that is, the number of symbols included in the second symbol set is M. If A2 is less than or equal to P1, the network device may determine, according to the correspondence, the number M of symbols included in the second symbol set relative to the number M of symbols included in the third symbol set, where the number of symbols included in the second symbol set needs to be increased by 1 symbol, and since symbols other than the first symbol set do not include PUCCH resources, the number M of symbols included in the second symbol set is M +1 and the number M of symbols included in the first symbol set _max Minimum of (3), i.e., min (M +1, M) _max ). And the network equipment determines a second symbol set according to the number of the symbols and determines the PUCCH resources contained in the second symbol set as alternative PUCCH resources in a second time range.

TABLE 3

Resource demand degree P	Number of symbols
		P＜A1	max(M-1,1)
A1≤P＜A2	M
		A2≤P	min(M+1,M _max )

Wherein max (X, Y) represents taking the maximum value of X and Y, and min (X, Y) represents taking the minimum value of X and Y.

For another example, the corresponding relationship includes a corresponding relationship between a plurality of value ranges of the uplink resource demand degree and a plurality of level identifiers, and a corresponding relationship between a plurality of level identifiers and a plurality of symbol numbers. The network device may first determine, according to a correspondence between the plurality of value ranges and the plurality of level identifiers, a value range to which the utilization rate P1 of the uplink resource in the first time range belongs and a level identifier corresponding to the value range, and then determine, according to a correspondence between the plurality of level identifiers and the plurality of symbol numbers, that the symbol number corresponding to the level identifier is the symbol number included in the second symbol set. And the network equipment determines a second symbol set according to the symbol number, and takes the PUCCH resources contained in the second symbol set as alternative PUCCH resources for carrying UCI in a second time range.

In a specific example, the resource demand may be divided into 3 levels, i.e., high, medium, and low levels, and 3 value ranges of the resource demand may be determined by two threshold values, for example, as shown in table 4, where the two threshold values are Th _high And Th _low If P1 < Th _low The level of resource demand is low; if Th is _low ≤P1＜Th _high Resource, resourceThe grade of the demand degree is medium; if Th is _high Less than or equal to P1, and the grade of the resource demand degree is high. When the level of resource desirability is low, the number of symbols included in the second symbol set may be max (M-2, 1), where M is the number of symbols included in the third symbol set. When the level of the resource demand degree is middle, the number of symbols included in the second symbol set may be M; when the level of the resource requirement is high, the number of symbols included in the second symbol set may be min (M +1, M) _max ) Wherein M is _max The first set of symbols comprises the number of symbols. But the application is not limited thereto.

TABLE 4

Resource demand degree P	Grade	Number of symbols
			P＜Th _low	Is low with	max(M-1,1)
Th _low ≤P＜Th _high	In	M
			Th _high ≤P	Height of	min(M+1,M _max )

In another embodiment, the resource unit is a frequency domain resource.

Alternatively, the granularity of the frequency domain resources comprised by the set of frequency domain resources may be Resource Blocks (RBs), subcarriers, or groups of subcarriers.

For example, the plurality of PUCCH resources configured by the network device occupy a first frequency domain resource set in the frequency domain resources, and the network device determines a second frequency domain resource set in the first frequency domain resource set according to a resource requirement level (i.e., a first resource requirement level) of the uplink resource in a first time range. And the network equipment takes the PUCCH resources contained in the second frequency domain resource set as alternative PUCCH resource resources in a second time range, namely the first PUCCH resource.

The embodiment when the resource unit is a frequency domain resource is similar to the embodiment when the resource unit is a time domain resource, and only the resource types of the resource units included in the resource set are different, reference may be made to the above description of the embodiment when the resource unit is a time domain resource, and for the sake of brevity, details are not repeated here.

Optionally, the above two embodiments may be implemented in combination, and after determining the second symbol set and the second frequency domain resource set, the network device determines time-frequency resources where the second symbol set (i.e., the time domain resource set) intersects with the second frequency domain resource set, and uses PUCCH resources included in the time-frequency resources as alternative PUCCH resources in the second time range.

Or, the network device determines a time-frequency resource set according to the resource demand of the uplink resource in the first time range, and takes the PUCCH resource included in the time-frequency resource set as the alternative PUCCH resource in the second time range.

Optionally, the resource desirability includes one or more of:

the success rate of uplink control channel resource allocation, the failure rate of uplink control channel resource allocation, the utilization rate of uplink control channel resources, the utilization rate of uplink shared channel resources, the number of users establishing radio resource control connection or the proportion of first type users.

In one example, the resource requirement includes a PUCCH resource allocation success rate. The allocation success rate of the PUCCH resource is determined according to the number of times the PUCCH resource is successfully allocated and the number of times the PUCCH resource is requested in the first time range.

When downlink data of a terminal device arrives at a network device, the network device needs to allocate a data channel resource for carrying the data, for example, the data channel resource may be a Physical Downlink Shared Channel (PDSCH) resource. In addition, the network device needs to allocate (or request) a PUCCH resource corresponding to the PDSCH to the terminal device, so as to carry feedback information of the terminal device on the data. The feedback information is one of UCI, and the feedback information may be hybrid automatic repeat request (HARQ) information. After the network equipment allocates PDSCH resources for the data, if the PUCCH resources corresponding to the PDSCH resources are requested successfully, the network equipment sends the downlink data to the terminal equipment and indicates the corresponding PUCCH resources to be scheduled to bear HARQ information of the downlink data; if the PUCCH resource is not requested, it is considered that PUCCH allocation fails, and the network device needs to reallocate PDSCH resources for the data and allocate corresponding PUCCH resources.

For example, if the network device allocates the data to the corresponding PUCCH resource in the first uplink time unit after the data of the terminal device arrives, it is considered to be successful to request the PUCCH resource 1 time, or if the network device does not allocate the data to the corresponding PUCCH resource in the first uplink time unit after the data of the terminal device arrives, it is considered to be failed to request the PUCCH resource 1 time.

In the above, the network device is taken as an example to request the PUCCH for HARQ information, and the network device may also send CSI request PUCCH resources for the terminal device, which is not limited in the present application.

In this example, the network device counts a total number of times K that PUCCH resources are requested within a first time range, and a number of times K that PUCCH resources are successfully requested therein _Succ And determining the ratio of the times of successfully allocating the PUCCH resources in the first time range to the times of requesting the PUCCH resources in the first time range, namely determining the allocation success rate of the PUCCH resources in the first time range. PUCCH resourcesDistribution of source into power P _Succ Can be written as: p is _Succ ＝K _Succ and/K. The network device may determine alternative PUCCH resources available for carrying UCI in a second time range according to the allocated power of the PUCCH resource in the first time range.

Optionally, the multiple value ranges of the PUCCH resource allocation success rate correspond to multiple numbers of resource units (i.e., the corresponding relationship between the allocated power and the number of resource units), and the network device may determine P according to the corresponding relationship _Succ And determining the number of symbols corresponding to the value range as the number of resource units contained in the second resource set. And determining the PUCCH resources contained in the second resource set as alternative PUCCH resources which can be used for carrying UCI in a second time range.

For example, the network device allocates the power P according to the PUCCH resources in the first time range at the end of the first time range _Succ Threshold value judgment is carried out to obtain the distributed power level L _Succ . Such as:

if it is

Assignment success rate level L _Succ Is high; if not, then the mobile terminal can be switched to the normal mode,

if it is

Assignment success rate level L _Succ Is low; if not, then,

namely, it is

Assignment success rate level L _Succ Is medium.

For example, the resource unit is a time domain symbol, and the network device determines the allocated power level L according to the corresponding relationship between the multiple levels of allocated power and the multiple symbol numbers _Succ And the corresponding symbol number is the symbol number of the second symbol set, so that the PUCCH resources contained in the second symbol set are determined to be alternative PUCCH resources in a second time range.

In another example, the resource desirability includes an allocation failure rate of PUCCH resources. The allocated power of the PUCCH resource is determined according to the number of times of failure in allocating the PUCCH resource and the number of times of requesting the PUCCH resource in the first time range.

The network equipment counts the total times K of PUCCH resources in a first time range and the times K of failure of requesting the PUCCH resources _Fail And determining the ratio of the times of failure in the PUCCH resource allocation in the first time range to the times of PUCCH resource request in the first time range, namely determining the failure rate in the PUCCH resource allocation in the first time range. Failure rate P of PUCCH resource allocation _Fail Can be written as: p _Fail ＝K _Fail and/K is used. The network device may determine, according to the failure rate of PUCCH resource allocation in the first time range, an alternative PUCCH resource that may be used to carry UCI in the second time range.

For example, the network device may end in the first time range according to the failure rate P of PUCCH resource allocation in the first time range _Fail Threshold value judgment is carried out to obtain the distributed power level L _Fail . Such as:

if it is

Assignment success rate level L _Fail Is low; if not, then,

if it is

Assignment success rate level L _Fail Is high; if not, then the mobile terminal can be switched to the normal mode,

namely, it is

Assignment success rate level L _Fail Is medium.

For example, the resource unit is a time domain symbol, and the network device may determine L according to a corresponding relationship between the allocation failure rate level and the number of symbols _Fail And the corresponding symbol number is the symbol number of the second symbol set, so that alternative PUCCH resources which can be used for carrying UCI in a second time range are determined.

Or, the value range of the allocation success rate or the allocation failure rate of the PUCCH resources may directly correspond to the number of resource units, and the network device determines, according to the allocation success rate or the allocation failure rate of the PUCCH resources in the first time range, that the number of resource units corresponding to the range is the number of resource units included in the second resource set.

In another example, the resource requirement includes a utilization rate of PUCCH resources.

In one embodiment, the usage rate of the PUCCH resource is determined according to the total number of resource units occupied by the alternative PUCCH resource in the first time range, which is the number of resource units occupied by the second PUCCH resource carrying UCI in the first time range. And the second PUCCH resource is a standby PUCCH resource in the first time range.

In another embodiment, the network device may calculate a usage rate of a PUCCH resource of each uplink time unit in the first time range, where the usage rate of the PUCCH resource of the uplink time unit is the number M of resource units occupied by a second PUCCH resource that carries UCI in one time unit _occupied (i.e. the number of symbols included in the third resource set) the number M of resource units occupied by the alternative PUCCH resources included in the uplink time unit _total Ratio of (i.e. P) _unit ＝M _occupied /M _total . And the third resource set is a set of symbols occupied by alternative resources of the PUCCH resources in the first time range. And the network equipment calculates the average value of the utilization rates of the PUCCH resources of all uplink time units in the first time range, namely the utilization rate of the PUCCH resources in the first time range.

The network device may determine, according to the usage rate of the PUCCH resources in the first time range, alternative PUCCH resources available for carrying UCI in the second time range.

Optionally, the utilization rate P of PUCCH resources _used The plurality of value ranges correspond to a plurality of numbers of resource units (i.e. a corresponding relationship between the usage rate of the PUCCH resource and the number of resource units), and the network device may determine the usage rate P of the PUCCH resource in the first time range according to the corresponding relationship _used The value range to which the value belongs, thereby determining the valueThe number of symbols corresponding to the value range is the number of resource units included in the second resource set. And determining the PUCCH resources contained in the second resource set as alternative PUCCH resources which can be used for carrying UCI in a second time range.

For example, when the network device ends the first time range, according to the utilization rate of the PUCCH resource in the first time range, the resource utilization rate level L is obtained _used . Such as:

if it is

Resource utilization rate L _used Is high; if not, then,

if it is

Resource utilization rate L _used Is low; if not, then,

namely that

Resource utilization rate L _used Is medium.

For example, the resource unit is a time domain symbol, and the network device may determine L according to the correspondence between the resource usage level and the number of symbols _used And the corresponding symbol number is the symbol number of the second symbol set, so that alternative PUCCH resources which can be used for carrying UCI in a second time range are determined.

Or the value range of the utilization rate of the PUCCH resource may directly correspond to the number of resource units, and the network device determines, according to the range to which the utilization rate of the PUCCH resource in the first time range belongs, that the number of resource units corresponding to the range is the number of resource units included in the second resource set. Thereby determining alternative PUCCH resources in the second time range.

In another example, the resource requirement includes an unused rate of PUCCH resources. The unused rate of the PUCCH resources is determined according to the number of resource units occupied by the second uplink control channel resources which do not bear the UCI in the first time range and the number of resource units occupied by the alternative PUCCH resources.

In another example, the resource requirement includes usage of PUSCH resources. The usage rate of the PUSCH resources is determined according to the size of the scheduled PUSCH resources in the first time range and the total resource size of the PUSCH resources.

In another example, the resource desirability includes an unused rate of PUSCH resources. The unused rate of the PUSCH resource is determined according to the size of the PUSCH resource which is not scheduled in the first time range and the total resource size of the PUSCH resource.

Optionally, the PUSCH resource size may be determined according to the number of resource elements occupied by the PUSCH, for example, the PUSCH resource size may be determined according to the number of RBs occupied by the PUSCH resource, or according to the number of symbols occupied by the PUSCH resource, or according to both the number of RBs occupied by the PUSCH resource and the number of symbols.

For a specific embodiment of the network device determining the non-usage rate of the PUCCH resource, the usage rate of the PUSCH resource, or the non-usage rate in the first time range, reference may be made to the description of the network device determining the usage rate of the PUCCH in the first time range, and for brevity, details are not repeated here.

In another example, the resource requirement includes a number of users establishing an RRC connection with the network. In other words, the number of users establishing RRC connection with the network in a time range may be used to characterize the resource requirement in the time range.

The network device may determine the alternative PUCCH resource in the second time range according to the number of users establishing RRC connection with the network in the first time range. Optionally, the network device may determine the second resource set according to the number of users establishing RRC connection with the network in the first time range, and then determine that the PUCCH resource included in the second resource set is the alternative PUCCH resource in the second time range.

Optionally, a plurality of value ranges of the number of users may correspond to a plurality of numbers of the resource unit, or a plurality of value ranges of the number of users may correspond to a plurality of user number classes, and the plurality of user number classes correspond to a plurality of numbers of the resource unit.

For example, the network device establishes RRC with the network according to the first time range at the end of the first time rangeNumber of connected users N _user Threshold value judgment is carried out to obtain the resource demand level L _user . Such as:

if it is

Resource demand level L _user Is high; if not, then,

if it is

Resource demand level L _user Is low; if not, then,

namely that

Resource demand level L _user Is medium.

For example, the resource unit is a time domain symbol, and the network device can determine L according to the corresponding relationship between the number of users establishing RRC connection with the network and the number of symbols _user And the corresponding symbol number is the symbol number of the second symbol set, so that alternative PUCCH resources which can be used for carrying UCI in a second time range are determined.

In another example, the resource desirability includes a first type of user proportion. Wherein the first type of user is a user whose uplink signal quality is below a signal quality threshold. The first type of user proportion in the first time range is based on the number N of users with signal quality lower than the signal quality threshold value in the first time range _{SINR_low} And the total number N of users establishing radio resource control connection in the first time range _user And (4) determining. Such as the first type user ratio P _{SINR_low} ＝N _{SINR_low} /N _user 。

For example, at the end of the first time range, the network device is based on the first type user ratio P in the first time range _{SINR_low} Threshold value judgment is carried out to obtain the resource demand level L _{SINR_low} . The network device can determine L according to the corresponding relation between the allocated power level and the symbol number _{SINR_low} The corresponding number of symbols is the number of symbols of the second symbol set, thereby determining the number of symbols which can be used for carrying UCI in the second time rangeAlternative PUCCH resources.

Optionally, the above examples may be implemented in combination with each other, that is, the resource requirement degree may include multiple items of the following parameters:

the radio resource control connection establishment method comprises the following steps of PUCCH resource allocation success rate, PUCCH resource allocation failure rate, PUCCH resource utilization rate, PUSCH resource utilization rate, the number of users establishing radio resource control connection or first type user proportion.

In one example, the resource desirability may include a PUCCH resource allocation success rate P _Succ And the number N of users establishing a radio resource control connection _user . The network equipment can allocate the success rate P according to the PUCCH resources in the first time range _Succ And usage rate of PUSCH

Alternative PUCCH resources available for carrying UCI in the second time range are determined.

Optionally, the network device may allocate the success rate P according to the PUCCH-based resource based on the first time range _Succ Determined allocation into power level Lsucc, and PUSCH-based usage

Determined resource demand level

And determining alternative PUCCH resources in a second time range.

For example, the resource unit is a time domain symbol, and the success rate level L is allocated _Succ And a resource demand level L _user May correspond to a symbol number, which may be determined based on the number of symbols M occupied by the alternative PUCCH resources in the first time range. As shown in Table 5, if the success rate level L is assigned _Succ Is low, resource demand level L _user If so, the network device may determine, based on the correspondence, that the number of symbols occupied by the alternative PUCCH resources in the second time range is 1 more than the number of symbols occupied by the alternative PUCCH resources in the first time range, and the number of symbols occupied by the alternative PUCCH resources in the second time range cannot be 1 more than the number of symbols occupied by the alternative PUCCH resources in the first time rangeExceeding the total number of symbols M contained in the first set of symbols _max That is, the network device may determine that the second set of symbols contains a number of symbols that is min (M +1, M) _max ) And determining the PUCCH resource included in the second symbol set as an alternative PUCCH resource available for carrying UCI in the second time range.

TABLE 5

S230, the network device receives uplink data on the first PUSCH resource.

Accordingly, the terminal device transmits uplink data on the first PUSCH resource. The first PUSCH resource includes a partial resource of the configured PUCCH resource.

That is, the network device may adapt the usage of the resource by scheduling information (e.g., the first information) according to the demand. Even if the first PUSCH resource includes part or all of the PUCCH resources configured by the network device, the terminal device may consider that the network device has rewritten the usage of the resources, and the terminal device transmits uplink data on the first PUSCH resource in response to scheduling by the network device.

According to the scheme of the application, the network equipment can schedule PUCCH resources to transmit data when UCI transmission requirements are small or data transmission requirements are large, and the resource utilization rate and the uplink transmission rate can be improved. On the other hand, the network device may adjust the actually used PUCCH resource without reconfiguring the PUCCH resource for the terminal device through RRC signaling. The terminal device only needs to respond to the scheduling of the network device for uplink information transmission. The terminal equipment and the network equipment can achieve consensus, signaling overhead can be reduced, and resource utilization rate is further improved.
