Description

Resource allocation method, equipment and computer storage medium

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for resource allocation, and a computer storage medium.

Background

In a New Radio (NR) system of the fifth Generation (5G, 5th Generation), the system bandwidth supported by the NR is greatly increased, and the transmission bandwidth of the terminal may occupy only a part of the system bandwidth. Based on the above, in order to improve scheduling efficiency, NR introduces a bandwidth Part (BWP) concept, enabling frequency domain resource allocation in a smaller range than system bandwidth. In NR, one carrier may contain up to four Bandwidth parts (BWPs), each BWP mainly includes three parameters: base parameter set Numerology, center frequency point, and bandwidth.

In the existing protocol, BWP can be activated or switched based on the indication information contained in the BWP indication field in the DCI signaling, and if the DCI signaling does not contain the BWP indication field, only the currently effective BWP can be used for data transmission, and dynamic configuration of BWP cannot be implemented, where the currently effective BWP is usually the default BWP, and the default BWP is considered for UE energy saving, and the bandwidth is usually smaller, and cannot be adapted to the requirement of low-latency high-reliability Communication (UR LL C, Ultra Reliable & L ow L mechanisms) service.

The embodiment of the invention provides a resource allocation method, resource allocation equipment and a computer storage medium. Under the condition that DCI signaling does not include a BWP indication domain, the dynamic configuration of BWP can be realized to meet the service requirement, and the flexibility of configuration is improved.

Detailed Description

So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

In the current research of 5G NR, taking the network architecture shown in fig. 1 as an example, a network device, such as a base station, specifically, an evolved Node B (eNB) or a 5G base station gNB may configure a plurality of BWPs for a User Equipment (UE) through Radio Resource Control (RRC) signaling, and then activate or switch a target BWP used for data transmission of the UE in Downlink Control Information (DCI). In detail, after the UE switches to the target BWP based on the DCI signaling, a timer is started to count, where the counting period indicates a configuration validation time period of the target BWP; and when the timing period is over, the UE switches to default BWP for data transmission.

For the embodiments of the present invention, a UE may also be referred to as a terminal 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, where the terminal device may be a Station (ST) in a Wireless local Area Network ("W L AN"), a cellular phone, a cordless phone, a Session Initiation Protocol ("SIP") phone, a Wireless local loop ("W L o L op"), a Personal Digital Assistant ("PDA") device, a handheld device with Wireless communication capability, a computing device, or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, and a next-generation communication system, such as a wearable terminal in a fifth-generation communication ("fifth-generation communication" 5 ") device, a wearable device, a Mobile terminal, a wearable device, or other processing device connected to a Wireless modem, a wearable device, or a Mobile Network, and so on-premise equipment (" MN — wearable device "), or a wearable Network, such as a wearable terminal, or a wearable Network, may also be referred to as a wearable Network and commonly-developed in embodiments of the present invention.

For the Format of DCI signaling, that is, DCI Format, currently, the DCI Format for UE-specific includes four modes, that is, an uplink fallback mode DCI Format0_0, an uplink normal mode DCI Format0_1, a downlink fallback mode DCI Format1_0, and a downlink normal mode DCI Format1_ 1. In the above four modes, the DCI Format of the two conventional modes includes a BWP indication field, which may be used to indicate the BWP used by the current data; but no BWP indication field is included in DCI Format for both fallback modes. Therefore, for DCI formats in two fallback modes, for the case that the timer is expired, only default BWP can be used for data transmission; and if the timer does not time out, performing data transmission according to the BWP indicated by the DCI starting the timer. Thereby making it impossible to dynamically configure for BWP in the fallback mode.

In addition, for special service requirements in 5G, such as low latency high reliability Communication (UR LL C, Ultra Reliable & L ow L opportunity Communication) service, in order to reduce transmission latency, a new DCI Format is introduced, that is, a compressed DCI Format, which is improved based on a fallback DCI Format and has no BWP indication field and therefore cannot be configured dynamically for BWP, however, in order to reduce transmission latency, UR LL C service generally configures a larger subcarrier spacing, for example, the subcarrier spacing of enhanced Mobile BroadBand (eMBB, enhanced Mobile BroadBand band) service may use kHz 15, and the subcarrier spacing of UR LL C service may use 30kHz, so to protect the transmission requirements of UR LL C service, BWP still needs to be configured dynamically and specifically.

Based on the problems occurring in the above description, the present application proposes the following embodiments.

Example one

Referring to fig. 2, it shows a method for resource configuration provided in an embodiment of the present invention, where the method is applied to a UE, and the method includes:

s201: receiving control information;

s202: transmitting the data scheduled by the control information; wherein the bandwidth part BWP configuration corresponding to the data scheduled by the control information is determined by a mapping relation between the parameter of the control information and the BWP configuration corresponding to the data scheduled by the control information.

Through the technical scheme shown in fig. 2, it can be seen that the network device implicitly indicates the BWP configuration of the information through the parameters of the control information when sending the control information, so that the UE obtains the BWP configuration by using the parameters of the control information used by the network device in the process of receiving the control information sent by the network device, and does not need to indicate the BWP configuration through a DCI indication field in a DCI display manner, which not only reduces the length of DCI Format, but also can dynamically configure the BWP.

For the technical solution shown in fig. 2, a mapping relationship between the parameter of the control information and the bandwidth portion BWP configuration information corresponding to the data scheduled by the control information is a mapping relationship agreed by a protocol; or, the mapping relationship between the parameter of the control information and the bandwidth part BWP configuration information corresponding to the data scheduled by the control information is configured through signaling. And the above signaling configuration may preferably be through higher layer signaling configuration. Typically, the higher layer signaling is RRC signaling, Media Access Control (MAC) Control Element (CE) signaling.

Specifically, since the BWP configuration information is indication information for configuring the BWP, typically 4 BWPs are semi-statically configured for one carrier. Thus, in the present embodiment, the 4 BWPs may be numbered separately, and may be numbered as BWP1, BWP2, BWP3 and BWP4 in sequence. The configuration information corresponding to these four BWPs are the configuration information for BWP1, the configuration information for BWP2, the configuration information for BWP3 and the configuration information for BWP4, respectively. The above four BWPs and the corresponding four BWP configuration information are preferably applied to the exemplary illustration of the present embodiment, and are not described in detail later.

For the technical solution shown in fig. 2, the parameters of the control information include:

downlink control information DCI Format Format; and/or the presence of a gas in the gas,

at least one indication field in the DCI; and/or the presence of a gas in the gas,

a search space in which the DCI is located; and/or the presence of a gas in the gas,

and controlling resource set CORESet where the DCI is located.

It is understood that, in addition to the above transmission parameter examples, other transmission parameters capable of implicitly indicating the BWP configuration information may still be applied to the technical solution of the embodiment of the present invention, and are not described herein again. The embodiment of the present invention specifically describes the technical solution shown in fig. 2 based on the transmission parameter example.

Example 1

For DCI Format, the DCI Format may specifically include: the user-specific DCI format not including the BWP indication field. It should be noted that, in the existing DCI Format, neither the compressed DCI Format nor the fallback DCI Format includes the BWP indication field.

Based on this, the determining, by a mapping relationship between parameters of control information and BWP configurations corresponding to the data scheduled by the control information, of the bandwidth part BWP configurations corresponding to the data scheduled by the control information includes:

determining the BWP configuration corresponding to the data scheduled by the compressed DCI Format as first BWP configuration information corresponding to the DCI Format as compressed DCI Format; and/or

Determining BWP configuration corresponding to data scheduled by the fallback DCI Format as second BWP configuration information corresponding to the DCI Format being the fallback DCI Format; and/or

And determining the BWP configuration corresponding to the data scheduled by the DCI format for scheduling the first service as third BWP configuration information, corresponding to the DCI format for scheduling the first service.

Typically, the first BWP is configured as a large bandwidth BWP for supporting low latency high reliability transmission. And the second BWP is configured as a small bandwidth BWP for supporting power-saving transmission.

For example, when the DCI includes the BWP indication field, configuring the BWP according to the content indicated in the BWP indication field; in the existing DCI Format, neither the compressed DCI Format nor the fallback DCI Format includes the BWP indication field, and based on this, the corresponding BWP configuration may be determined for two DCI not including the BWP indication field. Setting the configuration information of the compressed DCI Format corresponding to the BWP1, and setting the configuration information of the fallback DCI Format corresponding to the BWP2, when the UE receives the information, the UE may determine the corresponding BWP configuration information according to the DCI Format used by the network device to send the information.

In addition, the first service takes UR LL C service as an example, the corresponding DCI Format is a compressed DCI Format, and the configuration information of the compressed DCI Format corresponding to BWP1 is set, so that after the UE determines that the DCI Format is the compressed DCI Format according to the UR LL C service type, the UE can obtain the configuration information of the corresponding BWP1 based on the compressed DCI Format corresponding to the UR LL C service.

Example two

The Time domain resource indication field of the DCI may include a Transmission Time Interval (TTI) length L ength and a Physical Downlink Shared CHannel (PDSCH) type, and the frequency domain resource indication field of the DCI may exemplarily include a frequency domain resource indication type and a frequency domain scheduling bandwidth.

For the time domain resource indication field of the DCI, optionally, the determining, by a mapping relationship between a parameter of the control information and a BWP configuration corresponding to the data scheduled by the control information, a bandwidth portion BWP configuration corresponding to the data scheduled by the control information includes:

judging whether TTI L ength meets a preset first condition or not;

and determining BWP configuration information corresponding to a preset first condition corresponding to the TTI L ength meeting the preset first condition.

Optionally, the determining, by a mapping relationship between a parameter of control information and a BWP configuration corresponding to the data scheduled by the control information, a bandwidth part BWP configuration corresponding to the data scheduled by the control information includes:

judging whether the type of the Physical Downlink Shared Channel (PDSCH) meets a preset second condition or not;

determining BWP configuration information corresponding to a second condition corresponding to the PDSCH type satisfying the preset second condition.

Taking TTI L ength as an example, the preset first condition may be that the preset length is smaller than the set length threshold N, and the preset first condition corresponds to the configuration information of BWP1, and then when the DCI Format is a specific DCI Format and TTI L ength is smaller than N, the configuration information is determined to be BWP 1.

And the PDSCH type may include at least two types, and the second condition may be a type to which the PDSCH type is conformed. Specifically, there may be corresponding BWP configuration information for each type, and after determining the type to which the PDSCH type conforms, the BWP configuration information corresponding to the type is determined.

For the frequency domain resource indication field of the DCI, optionally, the bandwidth part BWP configuration corresponding to the data scheduled by the control information is determined by a mapping relationship between parameters of the control information and the BWP configuration corresponding to the data scheduled by the control information, including:

judging whether the frequency domain resource indication type meets a preset third condition or not;

and determining BWP configuration information corresponding to a third condition corresponding to the frequency domain resource indication type meeting a preset third condition.

judging whether the frequency domain scheduling bandwidth meets a preset fourth condition or not;

and determining BWP configuration information corresponding to a preset fourth condition corresponding to the frequency domain scheduling bandwidth meeting the preset fourth condition.

Taking the frequency domain resource indication Type as an example, the preset third condition may be that the frequency domain resource indication Type is Type B, and the third condition is set to correspond to the configuration information of BWP1, then when the DCI Format is a specific DCI Format, and the frequency domain resource indication Type is Type B, the configuration information is determined to be BWP 1. For example, when there is no BWP indication field in the DCI and the frequency domain resource indication Type is Type B, it is determined as configuration information of BWP 1; alternatively, when the DCI is a compressed DCI Format and the frequency domain resource indication Type is Type B, it is determined as configuration information of BWP 1. It is understood that for non-specific DCI formats, existing protocol rules may still be employed to determine BWP configuration. This embodiment will not be described in detail. Note that Type B is typically used for short TTI length scheduling.

The frequency-domain scheduling bandwidth may also set a fourth condition specifically, and when the frequency-domain scheduling bandwidth conforms to the fourth condition and the DCI Format is a specific DCI Format, the frequency-domain scheduling bandwidth is determined to be the BWP configuration information corresponding to the fourth condition.

For example, when the frequency-domain bandwidth is larger than the BWP bandwidth determined by the currently existing rule, the frequency-domain scheduling bandwidth may be considered to meet a fourth condition, based on which the BWP configuration may be determined based on the BWP configuration information corresponding to the fourth condition, otherwise, if the fourth condition is not met, the BWP is determined according to the currently existing rule.

Example three

For the search space where the DCI is located, determining, by a mapping relationship between a parameter of control information and a BWP configuration corresponding to the data scheduled by the control information, a bandwidth part BWP configuration corresponding to the data scheduled by the control information, including:

judging whether the search space where the DCI is located meets a preset fifth condition or not;

and determining the BWP configuration information corresponding to a fifth condition corresponding to the preset fifth condition that the search space where the DCI is located meets the preset fifth condition.

Specifically, the search space in which the DCI is located may also specifically include a search space set. Taking the search space period as an example, the fifth condition may be that the search space period is less than a set period threshold M, and the fifth condition is set to correspond to the configuration information of BWP1, then when the DCI Format is a specific DCI Format, and the search space period is less than M, the configuration information of BWP1 is determined. For example, when there is no BWP indication field in DCI and the search space period is less than M, it is determined as configuration information of BWP 1; alternatively, when the DCI is a compressed DCI Format and the search space period is less than M, it is determined as configuration information of BWP 1. It is understood that for non-specific DCI formats, existing protocol rules may still be employed to determine BWP configuration. This embodiment will not be described in detail.

Example four

For the CORESet where the DCI is located, determining, by a mapping relationship between a parameter of the control information and a BWP configuration corresponding to the data scheduled by the control information, a bandwidth part BWP configuration corresponding to the data scheduled by the control information, including:

judging whether the CORESet where the DCI is located meets a preset sixth condition;

and determining BWP configuration information corresponding to the fifth condition corresponding to the CORESet meeting a preset sixth condition.

Specifically, taking the time domain length of the CORESet where the DCI is located as an example, the sixth condition may be that the time domain length of the CORESet is smaller than the set symbol length L, and the sixth condition is set to correspond to the configuration information of BWP1, then when the DCI Format is the specific DCI Format and the time domain length of the CORESet is smaller than L, the configuration information is determined to be BWP 1.

By the resource configuration method provided by the embodiment, the BWP is configured implicitly through the parameters of the control information, and the indication is performed through the DCI indication field without being displayed in the DCI, so that not only is the length of the DCI Format reduced, but also the BWP can be configured dynamically.

Example two

s301: sending control information;

s302: transmitting data scheduled by the control information; wherein the bandwidth part BWP configuration corresponding to the data scheduled by the control information is determined based on a mapping relation between the preset parameters of the control information and the BWP configuration.

Through the technical scheme shown in fig. 3, it can be seen that the network device implicitly indicates BWP configuration through the parameter of the control information, so that indication is performed through a DCI indication field without being displayed in DCI, which not only reduces the length of DCI Format, but also dynamically configures BWP.

In the foregoing scheme, the parameter of the control information may include:

and controlling resource set CORESet where the DCI is located.

It should be noted that, based on the mapping relationship between the preset parameters of the control information and the bandwidth part BWP configuration information, the parameters of the control information each have corresponding BWP configuration information, so that when the UE receives the information sent by the network device, the UE acquires the corresponding BWP configuration information according to the parameters of the control information. For the UE specific acquisition process, refer to embodiment one, and are not described herein again.

It is understood that, in addition to the above examples of parameters of the control information, other parameters of the control information capable of implicitly indicating the BWP configuration information may still be applied to the technical solution of the embodiment of the present invention, and are not described herein again.

For the parameters of the control information, the DCI Format includes: the user-specific DCI format not including the BWP indication field.

For the above transmission parameters, the at least one indication field in the DCI may specifically include: a time domain resource indication field of the DCI; and/or, a frequency domain resource indication field of the DCI.

For the time domain resource indication field of the DCI, the time domain resource indication field may specifically include a transmission time interval length TTI L ength or a physical downlink shared channel PDSCH type.

For the frequency domain resource indication field of the DCI, the method may specifically include: the frequency domain resource indicates a type or a frequency domain scheduling bandwidth.

In the above solution, a mapping relationship between the parameter of the control information and the BWP configuration information of the bandwidth part corresponding to the data scheduled by the control information is a mapping relationship agreed by a protocol; or, the mapping relationship between the parameter of the control information and the bandwidth part BWP configuration information corresponding to the data scheduled by the control information is configured through signaling. And the above signaling configuration may preferably be through higher layer signaling configuration. Typically, the higher layer signaling is RRC signaling, MAC CE signaling.
