Description

Resource allocation and uplink transmission method, base station and terminal

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a resource allocation and uplink transmission method, a base station, and a terminal.

Background

The New Radio (New Radio, abbreviated as NR) supports semi-static Time Division Duplex (TDD) configuration (semi-static UL/DL configuration), which includes cell-level uplink and downlink configuration (UL-DL-configuration-common, UL-DL-configuration-common2) and user-level uplink and downlink configuration (UL-DL-configuration-dedicated) to adapt to the requirement of dynamic change of uplink and downlink service ratio, and may configure slot/symbol-level uplink and downlink directions, including three formats of uplink (uplink), downlink (downlink) and flexible (flexible). An example of a typical semi-static UL/DL configuration is shown in FIG. 1: a subcarrier interval of 30kHz (kilohertz), a 2.5ms double Period, 4 symbols (symbol) reserved as a Guard Period (GP) for uplink and downlink switching, which can realize that 8 synchronization signal blocks/Physical broadcast Channel blocks (SS/PBCH blocks) are sent in the first 4 slots of the first Period (i.e., 2.5ms Period 1 in fig. 1), a 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 traffic 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 (PUCCH for short) and improve reliability, NR supports repeated transmission of a long Random Access sequence format (long PUCCH frequency) in k continuously available slots (slots), and symbol configuration (symbol allocation) in each slot is the same; "available" refers to either semi-static configuration or to an uplink or flexible configuration of the dynamic (dynamic) Slot Format Indication (SFI) configuration.

In order to improve the reliability of a Physical Uplink Shared Channel (PUSCH), NR supports PUSCH retransmission (retransmission), that is, a same Transport Block (TB) is repeatedly transmitted in k continuously available slots, and symbol allocation in each slot is the same; for grant-based multi-slot scheduling, "available" refers to either semi-static configuration or dynamic SFI configured uplink or flex, and for grant-free uplink pusch retransmission, "available" refers to either semi-static configuration configured uplink or dynamic SFI configured uplink.

In order to support a Sounding Reference Signal (SRS) round-robin transmission mechanism for one-transmission-four-reception (1T4R), the SRS needs to occupy at least two slots for transmission, and positions (slots) of 4 SRS in the two slots are still under discussion.

According to the current conclusion of NR, the problem of uplink transmission collision of GP, PUCCH/PUSCH/SRS and the like can occur:

from the perspective of a base station, a terminal (User Equipment, UE for short, also called User Equipment) is configured with a flexible resource (GP), and the flexible resource includes the GP therein;

from the UE perspective, the received configuration is configured as flexible resource, but the terminal does not know the specific location of the GP in the flexible resource and the occupied length.

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

In order to reduce the collision problem of the uplink transmission and the GP, it is desirable that flexible resource is not used for the uplink transmission; but from the perspective of resource utilization and flexibility, uplink transmission needs to be performed at flexible resource.

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

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

Referring to fig. 3, fig. 3 is a flowchart illustrating 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: sending configuration information of flexible resources to a terminal, wherein the configuration information comprises: and indication information for indicating whether uplink transmission can be performed on the flexible resources.

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 or not according to the allocation information, thereby reducing the collision problem of uplink transmission and GP, improving the flexibility and utilization rate of resource scheduling and reducing time delay.

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

The flexible resources configured through the high-level signaling may include semi-statically configured flexible resources (e.g., flexible slots, flexible symbols, etc.), and the flexible resources configured through the physical-level control signaling may be dynamically configured flexible resources.

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

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, there are various ways for the indication information, which are exemplified below.

As a first alternative embodiment:

the length of the indication information is 1bit, and is used for indicating that uplink transmission can be performed/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 the 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 means that the flexible resource is not available for any type of uplink transmission (including but not limited to PUCCH, PUSCH, SRS, PRACH, etc.); if the indication information is "enable", it indicates that any type of uplink transmission can be performed on the flexible resource.

The bit of the indication information can be set to 0 to indicate a disable state, and 1 to indicate an enable state; of course, the bit of the indication information may be set to 1 to indicate a disable state and 0 to indicate an enable state, which is not a limitation of 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 is usable for performing the uplink transmission of the corresponding type, and disable indicates that the flexible resource is not usable for performing the uplink transmission of the corresponding type.

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

As a third alternative embodiment:

the flexible resource includes M symbols, the M symbols 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.

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

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

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 }, where enable indicates that uplink transmission can be performed on symbols of the corresponding portion, and disable indicates that uplink transmission cannot be performed on symbols of the corresponding portion.

Taking fig. 4 as an example, the flexible resource 41 includes a plurality of symbols, and is divided into 3 parts, i.e., 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, the 1 st bit corresponds to the first partial symbol 411, the 2 nd bit corresponds to the second partial symbol 412, and the 3 rd bit 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 can be performed on the first partial symbol 411 and the second partial symbol 412.

(3.2) the length of the indication information is N x 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 the Q part symbols corresponds to one bit in each Q bit; each bit of the indication information is used for indicating that uplink transmission of a corresponding type can be performed/cannot be performed on a symbol of a corresponding part. Wherein N is a positive integer greater than or equal to 2.

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

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, it indicates a disable state, and when it is 1, it indicates an enable state. There are 4 types of uplink transmissions including PUCCH, PUSCH, SRS, and PRACH.

The indication information is 110011010100, the length is 12 bits, the 0-2 bits "110" correspond to PUCCH transmission, the 3-5 bits "011" correspond to PUSCH transmission, the 6-8 bits "010" correspond to SRS transmission, and the 9-11 bits "100" correspond 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 and second

partial symbols

411 and 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 and third

partial symbols

412 and 413 can be used for PUSCH transmission.

Bits 6-8 "010" indicate that the first and third

partial symbols

411 and 413 cannot be used for SRS transmission and that 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 can be divided into Q parts as follows:

the Q part of the symbol, each of the pre-mod (M, Q) parts comprising

Each of the post-Q-mod (M, Q) portions comprising

A symbol.

As a fourth alternative embodiment:

(4.1) the indication information 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 that can/cannot perform uplink transmission.

For example, referring to fig. 5, if the configured flexible resources are the first 10 symbols (i.e., symbols 0-9) of a timeslot, the position information in the indication information is used to indicate that symbols 2-5 of the timeslot cannot be used for uplink transmission, which means that symbols 2-5 cannot be used for any type of uplink transmission.

(4.2) the indication information includes: n location 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 a flexible resource 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 corresponding types of uplink transmission.

Still referring to fig. 5, if the configured flexible resources are the first 10 symbols (i.e. symbols 0 to 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 indicates that symbols 2 to 5 of a slot cannot be used for uplink transmission, the 2 nd position information indicates that symbols 3 to 6 cannot be used for uplink transmission. Symbols 2 to 5 indicating 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 location information includes at least two of: a start symbol, a symbol number, and an end symbol of a resource that can/cannot be used for uplink transmission in the flexible resources;

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

Preferably, the position information is separately or jointly encoded.

For example, the location information may be in the following 3 ways: (1) starting symbol + number of symbols; (2) start symbol + end symbol; (3) the number of symbols and the end symbol. If the position information is in the mode (1), the 2 values of the starting symbol and the number of symbols can 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 flowchart illustrating an uplink transmission method according to a second embodiment of the present invention, where 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 resources;

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 the available uplink transmission resource according to the configuration information, and then performs 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;

and (4) transmitting the PRACH.

In the embodiment of the invention, a terminal receives configuration information which is issued by a base station and aims at whether flexible resource can carry out uplink transmission or not, and determines whether a 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, performing corresponding uplink transmission on the determined resource according to high-level configuration or dynamic scheduling; eliminating uplink transmission on the configured/scheduled resource if one or several symbols of the resource are not available uplink transmission resources.

For uplink transmission configured by higher layers (for example, including Type 1grant-free transmission, Type2grant-free transmission excluding other uplink transmission scheduled by first DCI), the "available" indicates that the resource configured by the semi-static UL/DL configuration as uplink/flex and the resource configured by the dynamic SFI as uplink are configured, and is indicated as "available" by the configuration information or not indicated as "unavailable" by the configuration information.

For uplink transmission (e.g., including multi-slotted pusch/PUCCH scheduling, SRS) configured (i.e., dynamically scheduled) by physical layer control signaling, "available" refers to a resource configured as uplink/flexible by semi-static UL/dl configuration or dynamic SFI, and is indicated as "available" by the configuration information or not indicated as "unavailable" by the configuration information.

In the embodiment of the present invention, there are various ways for the indication information in the configuration information, which are described as examples below.

As a first alternative embodiment:

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

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

As a second alternative embodiment:

Still taking fig. 1 as an example, if the configuration information includes 3-bit indication information, the configuration information corresponds to PUCCH, PUSCH, and SRS transmissions, respectively. The configured flexible resource is 4 symbols: the last two symbols of the 4 th slot plus the first two symbols of the 5 th slot in cycle one, and the last two symbols of the 3 rd slot plus the first two symbols of the 4 th slot in cycle two. If the indication information of the 3bit is "enable disable" indicating that the configured flexible resource can be used for uplink transmission of the PUCCH and cannot be used for transmission of the PUSCH and the SRS, if the resource currently configured by the higher layer or dynamically scheduling the terminal for PUSCH or SRS transmission contains one or more symbols in the flexible resource, the terminal cancels the transmission.

As a third alternative embodiment:

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

Each part of the Q part of the symbols corresponds to one bit of the indication information, and each bit of the indication information is used for indicating that uplink transmission can be carried out on the corresponding part of the symbols;

Taking fig. 2 as an example, fig. 2 is a frame structure configured through semi-static UL/DL configuration, and if a base station sends configuration information to a terminal through a broadcast message or a UE-specific RRC message, the indication information in the configuration information is a 2-bit bitmap. The configured flexible resource is 10 symbols: the first 10 symbols of the 5 th slot in cycle one and the first 10 symbols of the 4 th slot in cycle two. The flexible resource is divided into 2 parts, wherein the first part of flexible resource is the first 5 symbols of the 5 th slot in the first period and the first 5 symbols of the 4 th slot in the second period; the second part of flexible resources are the last 5 symbols of the 5 th slot in the first period and the last 5 symbols of the 4 th slot in the second period.

The bitmap is 01(0 represents disable, 1 represents enable), that is, the first 5 symbols of the 5 th slot in the first period are resources which cannot be used for uplink transmission, and the last 5 symbols are resources which can be used for uplink transmission; the first 5 symbols of the 4 th slot in the second period are resources that cannot be used for uplink transmission, and the last 5 symbols are resources that can be used for uplink transmission.

And if the current resource for uplink transmission through the high-level configuration or dynamic scheduling terminal comprises one or more symbols in the first part of flexible resources, the terminal cancels the transmission.

(3.22) the length of the indication information is N x Q bits.

Still taking fig. 2 as an example, if the base station sends configuration information to the terminal through a broadcast message or a UE-specific RRC message, the indication information in the configuration information is an 8-bit bitmap, and corresponds to four types of uplink transmissions, namely PUCCH, PUSCH, SRS, and PRACH. The configured flexible resource is 10 symbols: the first 10 symbols of the 5 th slot in cycle one and the first 10 symbols of the 4 th slot in cycle two. The flexible resource is divided into 2 parts, wherein the first part of flexible resource is the first 5 symbols of the 5 th slot in the first period and the first 5 symbols of the 4 th slot in the second period; the second part of flexible resources are the last 5 symbols of the 5 th slot in the first period and the last 5 symbols of the 4 th slot in the second period.

If the bitmap is 11100100 (0 represents disable and 1 represents enable), it indicates that the first part of flexible resources and the second part of flexible resources are both resources which can be used for uplink transmission of the PUCCH; the first part of flexible resources are resources which can be used for PUSCH uplink transmission, and the second part of flexible resources are resources which cannot be used for PUSCH uplink transmission; the first part of flexible resources are resources which cannot be used for SRS uplink transmission, and the second part of flexible resources are resources which can be used for SRS uplink transmission; the first part of flexible resources and the second part of flexible resources are both resources which cannot be used for PRACH uplink transmission.

And if the current resource for SRS uplink transmission through the high-layer configuration or the dynamic scheduling terminal comprises one or more symbols in the first part of flexible resources, the terminal cancels the transmission.

Each of the post-Q-mod (M, Q) portions comprising

A symbol.

As a fourth alternative embodiment:

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

Still taking fig. 2 as an example, if the base station sends the configuration information to the terminal through a broadcast message or a UE-specific RRC message, the configured flexible resource is 10 symbols: the first 10 symbols of the 5 th slot in cycle one and the first 10 symbols of the 4 th slot in cycle two.

The location information is used to indicate that the uplink transmission cannot be performed, and the starting symbol is 0 and the length is 5 (i.e. the number of included symbols is 5). That is, the first 5 symbols of the flexible resource (i.e. the first 5 symbols of the 5 th slot in the first period and the first 5 symbols of the 4 th slot in the second period) are resources that are not available for uplink transmission.

And if the current resource for uplink transmission through the high-level configuration or dynamic scheduling terminal comprises one or more symbols in the first 5 symbols in the flexbile resource, the terminal cancels the transmission.

(4.22) the indication information includes: n location information in the flexible resource.

each of the location information corresponds to one type of uplink transmission, and the location information is used for indicating the location of flexible resources that can/cannot be used for the corresponding type of uplink transmission;

Still taking fig. 2 as an example, if the base station sends 2 pieces of configuration information to the terminal through a broadcast message or a UE-specific RRC message, the configuration information corresponds to PUCCH and SRS transmission, respectively. The configured flexible resource is 10 symbols: the first 10 symbols of the 5 th slot in cycle one and the first 10 symbols of the 4 th slot in cycle two.

The location information is used to indicate that the location information cannot be used for uplink transmission, and in the first configuration information, the starting symbol is 0, and the length is 5 (that is, the number of included symbols is 5). That is, the first 5 symbols of the flexible resource (i.e., the first 5 symbols of the 5 th slot in the first period and the first 5 symbols of the 4 th slot in the second period) are resources that are not available for PUCCH uplink transmission.

In the second configuration information, the start symbol is 0 and the length is 4. That is, the first 4 symbols of the flexible resource (i.e., the first 4 symbols of the 5 th slot in the first period and the first 4 symbols of the 4 th slot in the second period) are resources that are not available for SRS uplink transmission.

And if the current resource for SRS uplink transmission through the high-layer configuration or the dynamic scheduling terminal comprises one or more symbols in the first 4 symbols in the flexbile resource, the terminal cancels the transmission.

Preferably, in (4.11) and (4.22), the position information includes at least two of: a start symbol, a symbol number, and an end symbol of a resource that can/cannot be used for uplink transmission in the flexible resources;
