Description

Resource allocation and uplink transmission method, base station and terminal

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method for configuring resources and uplink transmitting, a base station, and a terminal.

Background

New Radio (NR) supports semi-static UL/DL configuration (Time Division Duplexing, TDD) and includes three formats of uplink (uplink), downlink (downlink) and flexible (flexible) for cell level uplink and downlink configuration (UL-DL-configuration-common 2) and user level uplink and downlink configuration (UL-DL-configuration-allocated) to adapt to the requirement of dynamic change of uplink and downlink service ratio. An example of a typical semi-static UL/DL configuration is shown in fig. 1: 30kHz subcarrier interval, 2.5ms bi-Period, 4 symbols (symbol) are reserved as uplink and downlink conversion protection time slots (GP for short), 8 synchronization signal blocks/physical broadcast channel blocks (SS/PBCH blocks) can be fully generated in the first 4 slots of the first Period (i.e., 2.5ms Period 1 in fig. 1), and the physical random access channel (Physical Random Access Channel, PRACH) is sent in the 5 th slot, and the uplink and downlink ratio is adjusted in the second Period to adapt to the uplink and downlink service ratio. When far-end base station interference is considered, the GP needs to reserve more symbols, as shown in fig. 2.

In order to enhance the coverage performance of a physical random access channel (Physical Random Access Channel, abbreviated as PUCCH), improve reliability, NR supports repeated transmission of a long random access sequence format (long PUCCH hfmat) in k continuously available slots (slots), where symbol configuration (symbol allocation) in each slot is the same; "available" refers to semi-static configuration or uplink or flexible of dynamic (SFI) configuration of slot format indication (slot format indication, abbreviated SFI).

In order to improve the reliability of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), NR supports PUSCH retransmission (retransmission), i.e. repeated transmission of the same Transport Block (TB) in k consecutive available slots, with symbol allocation being the same in each slot; for grant-based multi-slot scheduling (grant based multi-slot scheduling), "available" refers to semi-static configuration or dynamic SFI configured uplink or flexible, for grant-free uplink data repeat transmission (grant-free PUSCH repetition), "available" refers to semi-static configuration configured uplink or flexible or dynamic SFI configured uplink.

In order to support a sounding reference signal (Sounding Reference Signal, abbreviated SRS) sounding mechanism, SRS needs to occupy at least two slots for transmission, and the positions (pattern) of 4 SRS within two slots are under discussion.

According to the current NR conclusion, the problem of uplink transmission conflict such as GP, PUCCH/PUSCH/SRS and the like occurs:

from the base station's point of view, by configuring a terminal (UE) for short, also called User Equipment, with a flexible resource (flexible resource) that includes a GP therein;

from the UE's point of view, the received configuration is flexible resource, but the terminal does not know the specific location and occupied length of the GP in the flexible resource.

According to the current conclusion of NR, uplink transmissions such as PUCCH/PUSCH/SRS can be transmitted on semi-static configured flexible resource, if the initial transmission of downlink control information (Downlink Control Information, DCI for short) scheduling can be avoided by dynamic scheduling and GP collision can be avoided, but for subsequent repeated transmission, the situation cannot be avoided. As shown in fig. 2, when the first PUCCH transmission is configured in the full uplink slot of the period two, the second PUCCH transmission will occur in the fifth slot of the next period one, and collide with the GP to generate inter-cell uplink and downlink interference.

In order to reduce collision problems of uplink with GP, it is desirable that flexible resource is not used for uplink; but from the point of view of resource utilization and flexibility, it is necessary to make an uplink transmission at flexible resource.

Therefore, how to reduce collision between uplink transmission and GP and improve utilization rate and flexibility of resources is a technical problem to be solved currently.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which are obtained by a person skilled in the art based on the described embodiments of the invention, fall within the scope of protection of the invention.

Referring to fig. 3, fig. 3 is a flowchart of a resource allocation method according to a first embodiment of the present invention, where the method is applied to a base station, and includes the following steps:

Step S31: transmitting configuration information of flexible resources to a terminal, wherein the configuration information comprises: and the indication information is used for indicating whether uplink transmission can be carried out on the flexible resource.

According to the resource allocation method provided by the embodiment of the invention, the base station sends the allocation information to the terminal, so that the terminal judges whether the flexible resource is the available uplink transmission resource according to the allocation information, thereby reducing the collision problem of uplink transmission and GP, improving the flexibility and the utilization rate of resource scheduling and reducing the time delay.

That is, the base station configures whether uplink transmission can be performed on the flexible resource for the user by means of a higher layer signaling configuration, where the higher layer signaling configuration may be a broadcasted higher layer message, such as a remaining minimum system information, other system messages, or other group common higher layer signaling; the higher layer signaling configuration may also be a terminal specific (UE-specific) higher layer signaling.

The flexible resources configured through the higher layer signaling may include flexible resources (such as flexible slot, flexible symbol, etc.) configured semi-statically, and the flexible resources configured through the physical layer control signaling may be flexible resources configured dynamically.

In the embodiment of the present invention, the type of uplink transmission includes at least one of the following:

PUCCH (physical uplink control channel) transmission;

PUSCH (physical uplink shared channel) transmission;

SRS (sounding reference signal) transmission;

PRACH (physical random access channel ) transmission.

In the embodiment of the present invention, the indication information may be in various manners, and is illustrated below.

As a first alternative embodiment:

the length of the indication information is 1bit, and the indication information is used for indicating that uplink transmission can be/cannot be performed on the flexible resource.

Specifically, the length of the indication information is 1bit, and the indication information includes two states { enable, disable }, where enable indicates that a flexible resource is available for uplink transmission, and disable indicates that the flexible resource is unavailable for uplink transmission.

That is, the indication information is "disable", which indicates that the flexible resource is not available for uplink transmission of any type (including, but not limited to PUCCH, PUSCH, SRS, PRACH, etc.); if the instruction information is "enable", it means that any type of uplink transmission can be performed on the flexible resource.

A bit of the indication information can be set to 0, which indicates a disable state, and a bit of the indication information can be set to 1, which indicates an enable state; of course, the bit of the indication information may be set to 1, which indicates a disable state, and 0 indicates an enable state, which is not limited by the present invention.

As a second alternative embodiment:

the uplink transmission comprises N types of uplink transmission, wherein N is a positive integer greater than or equal to 2;

Specifically, the length of the indication information is N bits, each bit corresponds to two states { enable, disable }, enable indicates that the flexible resource can be used for performing uplink transmission of a corresponding type, and disable indicates that the flexible resource cannot be used for performing uplink transmission of a corresponding type.

For example, the length of the indication information is 3 bits, corresponding to the 3 types of uplink transmission of PUCCH, PUSCH, SRS, respectively. If the instruction information is "disable enable enable", it indicates that the flexible resource cannot be used for uplink transmission of PUCCH and can be used for uplink transmission of PUSCH and SRS.

As a third alternative embodiment:

the flexible resource includes M symbols that are divided into Q parts, where Q is a positive integer greater than or equal to 1 and M is a positive integer greater than or equal to Q.

(3.1) the length of the indication information is Q bits.

Each part of symbols in the Q part of symbols corresponds to one bit of the indication information, and each bit of the indication information is used for indicating that uplink transmission can/cannot be performed on the symbols in the corresponding part.

Specifically, the indication information may be a bitmap (bitmap) with a length of Q bits, and the flexible resource is regarded as a reference resource, and includes M symbols, where the M symbols are divided into Q parts. Each of the Q bits corresponds to two states { enable, disable }, enable indicating that uplink transmission is possible on the corresponding portion of the symbols, and disable indicating that uplink transmission is not possible on the corresponding portion of the symbols.

Taking fig. 4 as an example, the flexible resource 41 includes a plurality of symbols, divided into 3 parts, namely a first part symbol 411, a second part symbol 412, and a third part symbol 413. The length of the indication information is 3 bits, bit 1 corresponds to the first partial symbol 411, bit 2 corresponds to the second partial symbol 412, and bit 3 corresponds to the third partial symbol 413. If the indication information is "enable enable disable", it indicates that the third partial symbol 413 cannot be used for any type of uplink transmission, and any type of uplink transmission may be performed on the first partial symbol 411 and the second partial symbol 412.

(3.2) the length of the indication information is n×q bits.

The uplink transmission comprises N types of uplink transmission, each Q bit of the indication information corresponds to one type of uplink transmission, and each part of symbols in the Q part of symbols corresponds to one bit in each Q bit; and each bit of the indication information is used for indicating that the corresponding type of uplink transmission can be/cannot be performed on the symbols of the corresponding part. Wherein N is a positive integer greater than or equal to 2.

Specifically, each of the n×q bits corresponds to two states { enable, disable }, where enable indicates that the corresponding type of uplink transmission can be performed on the corresponding portion of symbols, and disable indicates that the corresponding type of uplink transmission cannot be performed on the corresponding portion of symbols.

Optionally, the indication information is a bitmap with a length of n×q bits.

Still taking fig. 4 as an example, when the bit of the preset indication information is 0, the state is indicated as disable, and when the bit is 1, the state is indicated as enable. There are a total of PUCCH, PUSCH, SRS and PRACH 4 types of uplink transmissions.

The indication information is 110 011 010 100, the length is 12 bits, the 0-2 bit 110 corresponds to PUCCH transmission, the 3-5 bit 011 corresponds to PUSCH transmission, the 6-8 bit 010 corresponds to SRS transmission, and the 9-11 bit 100 corresponds to PRACH transmission. Wherein bits 0, 3, 6 and 9 of the indication information correspond to the first partial symbol 411, bits 1, 4, 7 and 10 correspond to the second partial symbol 412, and bits 2, 5, 8 and 11 correspond to the third partial symbol 413.

Bits 0-2 "110" indicate that the first partial symbol 411 and the second partial symbol 412 can be used for PUCCH transmission, and the third partial symbol 413 cannot be used for PUCCH transmission.

Bits 3-5 "011" indicate that the first partial symbol 411 cannot be used for PUSCH transmission, and the second partial symbol 412 and the third partial symbol 413 can be used for PUSCH transmission.

Bits 6-8 "010" indicate that the first partial symbol 411 and the third partial symbol 413 cannot be used for SRS transmission, and the second partial symbol 412 can be used for SRS transmission.

Bits 9-11 "100" indicate that the first partial symbol 411 can be used for PRACH transmission, and the second partial symbol 412 and the third partial symbol 413 cannot be used for PRACH transmission.

Preferably, the M symbols may be divided into Q parts as follows:

of the symbols of the Q part, each of the front mod (M, Q) parts includesEach of the post Q-mod (M, Q) parts comprises +.>And a symbol.

As a fourth alternative embodiment:

the indication information of (4.1) includes: location information indicating flexible resources that can/cannot be used for uplink transmission.

That is, the location information is an indication field for indicating flexible resources capable/incapable of uplink transmission.

For example, referring to fig. 5, if the flexible resource is the first 10 symbols (i.e., symbols 0-9) of a slot, the location information in the indication information is used to indicate that symbols 2-5 of the slot cannot be used for uplink transmission, meaning that symbols 2-5 cannot be used for any type of uplink transmission.

(4.2) the indication information includes: and N pieces of position information in the flexible resource.

The uplink transmission comprises N types of uplink transmission, wherein N is a positive integer greater than or equal to 2; each of the location information corresponds to one type of uplink transmission, and the location information is used to indicate a location of flexible resources that can/cannot be used for the corresponding type of uplink transmission.

That is, the location information is an indication field for indicating resources capable/incapable of uplink transmission of the corresponding type.

Still referring to fig. 5, if the flexible resource to be configured is the first 10 symbols (i.e., symbols 0-9) of a slot, the indication information includes 2 pieces of location information, the 1 st location information corresponds to SRS transmission and the 2 nd location information corresponds to PRACH transmission. If the 1 st position information is used to indicate that symbols 2 to 5 of a slot cannot be used for uplink transmission, the 2 nd position information is used to indicate that symbols 3 to 6 cannot be used for uplink transmission. Symbols 2 to 5, which indicate the slot, cannot be used for SRS transmission and symbols 3 to 6 cannot be used for PRACH transmission.

Preferably, in (4.1) and (4.2), the position information includes at least two of: a start symbol, a symbol number and an end symbol of a resource which can/cannot be used for uplink transmission in the flexible resource;

the starting symbol and the ending symbol both take a starting symbol of a time slot where the flexible resource is located or a starting symbol of the flexible resource (i.e. a first symbol of the flexible resource) as a reference point.

Preferably, the location information is encoded separately or jointly.

For example, the location information may be in the following 3 ways: (1) a start symbol+symbol number; (2) a start symbol+end symbol; (3) number of symbols and end symbol. If the position information is in the form (1), the 2 values of the start symbol and the number of symbols may be encoded separately or jointly.

Based on the same inventive concept, the invention also provides an uplink transmission method. Referring to fig. 6, fig. 6 is a flow chart of an uplink transmission method according to a second embodiment of the present invention, and the method is applied to a terminal, and includes the following steps:

step S61: receiving configuration information of flexible resources sent by a base station, wherein the configuration information comprises: indication information for indicating whether uplink transmission can be performed on the flexible resource;

Step S62: and carrying out uplink transmission according to the configuration information.

According to the uplink transmission method provided by the embodiment of the invention, the terminal receives the configuration information sent by the base station, judges whether the flexible resource is available uplink transmission resource according to the configuration information, and then carries out uplink transmission, so that the collision problem of uplink transmission and GP is reduced, the flexibility and the utilization rate of resource scheduling are improved, and the time delay is reduced.

Preferably, the type of uplink transmission includes at least one of:

PUCCH transmission;

PUSCH transmission;

SRS transmission;

PRACH transmission.

In the embodiment of the invention, the terminal receives the configuration information which is issued by the base station and can be used for carrying out uplink transmission aiming at flexible resource, and determines whether the configured/scheduled resource is an available uplink transmission resource or not according to the configuration information: if each symbol of the configured/scheduled resource is an available uplink transmission resource, corresponding uplink transmission is performed on the determined resource according to higher-layer configuration or dynamic scheduling; if one or several symbols of the configured/scheduled resources are not available uplink transmission resources, uplink transmission on said resources is eliminated.

For uplink transmissions of higher layer configurations (e.g., including Type 1grant-free transmission, type 2grant-free transmission excluding other uplink transmissions scheduled by the first DCI), "available" means that resources configured as uplink/flexible by semi-static UL/DL configuration and resources configured as uplink by dynamic SFI are indicated as "available" by the configuration information or as "unavailable" by the configuration information.

For uplink transmission (e.g., including multi-slot PUSCH/PUCCH scheduling, SRS) of a physical layer control signaling configuration (i.e., dynamic scheduling), "available" means configured as an uplink/flexible resource by semi-static UL/dl configuration or dynamic SFI, and indicated as "available" by the configuration information or not indicated as "unavailable" by the configuration information.

In the embodiment of the present invention, the indication information in the configuration information may be in various manners, and is illustrated below.

As a first alternative embodiment:

the length of the indication information is 1 bit, and the indication information is used for indicating that uplink transmission can be/cannot be carried out on the flexible resource;

the uplink transmission according to the configuration information includes:

Taking fig. 1 as an example, fig. 1 is a frame structure configured by semi-static UL/DL configuration, if a base station sends configuration information to a terminal through a broadcast message or a UE-specific RRC message, the configuration information includes 1bit indication information, and flexible resource configured is 4 symbols: the last two symbols of the 4 th slot plus the first two symbols of the 5 th slot in period one, and the last two symbols of the 3 rd slot plus the first two symbols of the 4 th slot in period two. The indication information of 1bit is "disable", and indicates that the configured flexible resource is not available for uplink transmission. If the current uplink transmission resource through the higher layer configuration or dynamic scheduling terminal contains one or more symbols in flexible resource, the terminal cancels the transmission.

As a second alternative embodiment:

the uplink transmission according to the configuration information includes:

Still taking fig. 1 as an example, if the configuration information includes 3bit indication information, the transmission corresponds to PUCCH, PUSCH, SRS respectively. Flexible resource configured are 4 symbols: the last two symbols of the 4 th slot plus the first two symbols of the 5 th slot in period one, and the last two symbols of the 3 rd slot plus the first two symbols of the 4 th slot in period two. The indication information of 3 bits is "enable disable disable", which indicates that the configured flexible resource can be used for PUCCH uplink transmission and not used for PUSCH and SRS transmission, and if the current resource for PUSCH or SRS transmission by the higher layer configuration or dynamic scheduling terminal includes one or more symbols in flexible resource, the terminal cancels the transmission.
