When the UE supports only one service type, if the physical uplink shared channel (PUSCH) allocated by the base station to the UE is not used to carry the uplink-shared channel (UL-SCH), or the UE is not allocated PUSCH resource, the UE may send an uplink scheduling request (Scheduling Request, SR) to the base station to request uplink transmission resources for the service of the service type; if the PUSCH can be used to carry the UL-SCH, the UE may send the base station through the PUSCH A buffer status report (Buffer Status Report, BSR), which requests uplink transmission resources for newly arrived service data of this service type.

However, when the UE supports multiple service types (such as eMBB and URLLC) at the same time, if the UE uses the PUSCH allocated by the base station to transmit eMBB service data, and the PUSCH can be used to carry the UL-SCH, then if the UE has URLLC Service data arrives, then due to the requirement of low latency of the URLLC service data or the UE takes a long time to process the BSR, the UE may not be able to send a BSR for the URLLC service data on the PUSCH, so the UE can send the SR to the base station, thinking the URLLC service data Quickly request uplink transmission resources. As such, when the UE sends the PUSCH and the SR, there may be a problem that the PUSCH and the SR collide.

detailed description

In the following, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The terms "first" and "second" in the description and claims of the embodiments of the present invention are used to distinguish different objects, rather than to describe a specific order of the objects. For example, the first type of business data and the second type of business data are used to distinguish different types of business data, rather than to describe a specific order of the business data. In the description of the embodiments of the present invention, unless otherwise stated, the meaning of “a plurality” means two or more.

The term "and / or" herein is an association relationship describing an associated object, which means that there can be three kinds of relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone These three situations. The symbol "/" in this text indicates that the associated object is or, for example, A / B means A or B.

In the embodiments of the present invention, words such as “exemplary” or “for example” are used as examples, illustrations or illustrations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present invention should not be construed as more preferred or more advantageous than other embodiments or designs. Rather, the use of the words "exemplary" or "for example" is intended to present the relevant concept in a concrete manner.

In the following, some concepts and / or terms involved in the PUSCH and SR processing methods and devices provided by the embodiments of the present invention are explained.

Uplink Scheduling Request (SR): If the UE has no uplink data to transmit, the base station does not need to allocate uplink transmission resources for the UE, otherwise transmission resources will be wasted. Therefore, the UE may send an SR to the base station to indicate to the base station whether the UE has uplink data to be transmitted, so that the base station determines whether to allocate uplink transmission resources for the UE. However, the UE can only indicate to the base station whether there is uplink data transmission through the SR, and cannot indicate how much uplink data the UE needs to transmit. The UE also needs to send a BSR to the base station to indicate to the base station how much data needs to be sent in the uplink buffer of the UE, so that the base station determines how much uplink transmission resources are allocated for the UE. Generally, after receiving the SR sent by the UE, the base station can allocate at least enough resources for the UE to send the BSR to the UE.

The base station can detect whether there is an SR report on the allocated SR resources. The SR is transmitted on the PUCCH resource, and the PUCCH resource for transmitting the SR is configured through the scheduling request resource identifier (Scheduling Request Resource Id) field of the IE: Scheduling Request Resource Configuration (Scheduling Request Resource Configuration). SR resources are allocated periodically, and different periods reflect different delay requirements. One UE can be configured with multiple SRs and differentiated by IE: Scheduling Request ID (Scheduling Request ID), and different SRs correspond to different logical channels / logical channel groups (that is, corresponding to the priority of data).

Physical uplink shared channel (PUSCH): The PUSCH can be used to carry UL-SCH and uplink control information (Uplink Control Information) (UCI). When the PUSCH is used to carry the UL-SCH (that is, the PUSCH with the UL-SCH), the UE can send uplink data through the PUSCH. At the same time, if the PUSCH and the physical uplink control carrying HARQ-ACK and Channel State Information (CSI) When a physical channel (PUCCH) conflicts, the UE can multiplex uplink data, HARQ-ACK, and CSI on the PUSCH for transmission. When the PUSCH is not used to carry the UL-SCH (that is, the PUSCH without the UL-SCH), that is, when the base station allocates the PUSCH resources, the PUSCH resources are only used to transmit HARQ-ACK and CSI, and are not used to transmit the UL-SCH. The PUSCH is not used for transmission of service data. When the PUSCH not used to carry the UL-SCH conflicts with the SR, the UE will discard the PUSCH and transmit the SR on the PUCCH resource corresponding to the SR.

It should be noted that in the NR system, the PUSCH may have different orthogonal frequency division multiplexing (OFDM) symbol length (for example, 2-14 OFDM symbols), and the PUCCH for transmitting the SR may be a short PUCCH ( (Such as 1 / 2OFDM symbol length), or long PUCCH (such as 4-14 OFDM symbol length), the period of SR can be 2 OFDM symbols, 7 OFDM symbols, 1 slot, or M slots (M is an integer of 1 or more).

The embodiments of the present invention provide a method and a device for processing PUSCH and SR. When the time domain resources of PUSCH and the time domain resources of SR overlap, the UE can determine the processing method of PUSCH and SR (the processing method is to transmit SR and discard PUSCH Or transmit PUSCH and SR), and process the PUSCH and SR according to this processing method. Since the time domain resources of the PUSCH and the time domain resources of the SR overlap, the UE can process the PUSCH and SR according to the determined processing method of the PUSCH and SR, that is, the UE can transmit the SR and discard the PUSCH, or transmit the PUSCH and SR. Therefore, the conflict between the PUSCH and the SR can be solved, so that the UE can quickly request the transmission resources of the second type of service data from the base station, so that the UE can transmit the second type of service data, which can reduce the transmission delay of the UE.

The PUSCH and SR processing methods and devices provided in the embodiments of the present invention can be applied to a communication system. Specifically, it can be applied to a process in which the UE processes PUSCH and SR based on the communication system.

Exemplarily, FIG. 1 shows a schematic architecture diagram of a communication system according to an embodiment of the present invention. As shown in FIG. 1, the communication system may include UE01 and a network-side device (such as base station 02).

Among them, the UE 01 and the base station 02 can establish a connection and communicate. Exemplarily, the UE 01 may send an SR to the base station 02 to indicate to the base station whether the UE has uplink data transmission. The UE may send a BSR to the base station to indicate to the base station how much data needs to be sent in the uplink buffer of the UE, so that the base station determines how many uplink transmission resources are allocated for the UE.

It should be noted that, in the embodiment of the present invention, the UE 01 and the base station 02 shown in FIG. 1 described above may be wirelessly connected. In order to more clearly illustrate the connection relationship between UE 01 and base station 02, FIG. 1 illustrates the connection relationship between UE 01 and base station 02 with a solid line.

A UE is a device that provides users with voice and / or data connectivity, a handheld device with wired / wireless connectivity, or other processing devices connected to a wireless modem. The UE may communicate with one or more core network devices through a radio access network (Radio Access Network, RAN). The UE can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. It can also be a portable, pocket, handheld, computer-built or vehicle-mounted mobile device that exchanges language with the RAN And / or data, for example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistant (Personal Digital Assistant) , PDA) and other equipment. The UE may also be called a user agent (User Agent) or a terminal device.

A base station is a device that is deployed in the RAN to provide wireless communication functions for the UE. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, and so on. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in the third generation mobile communication (3G) network, it is called a base station (Node B); in the LTE system It is called evolved NodeB, eNB or eNodeB; in the fifth generation mobile communication (5G) network, it is called gNB and so on. As communication technology evolves, the name "base station" may change.

The PUSCH and SR processing methods and equipment provided by the embodiments of the present invention will be described in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Based on the communication system shown in FIG. 1, an embodiment of the present invention provides a PUSCH and SR processing method. As shown in FIG. 2, the PUSCH and SR processing method may include

steps

201 and 202 described below.

Step 201: When the time domain resources of the PUSCH and the time domain resources of the SR overlap, the UE determines a processing mode of the PUSCH and the SR.

In the embodiment of the present invention, the PUSCH is used to transmit the first type of service data, and the SR is used to request the transmission resources of the second type of service data.

Optionally, in the embodiment of the present invention, the foregoing processing manner may be transmitting SR and discarding PUSCH; or transmitting PUSCH and SR.

Optionally, in the embodiment of the present invention, the priority of the second type of service data is higher than the priority of the first type of service data, and the priority is used to indicate data transmission priority, quality of service (Qos), Data transmission delay requirements or data transmission reliability requirements.

Optionally, in the embodiment of the present invention, the first type of service data may be eMBB service data, and the second type of service data may be URLLC service data. Among them, the URLLC service data data transmission priority is higher than the eMBB service data data transmission priority; or, the URLLC service data data transmission delay requirement is higher than the eMBB service data data transmission delay requirement (that is, the URLLC service data relative to The eMBB service data has a low latency requirement); or, the data transmission reliability requirement of the URLLC service data is higher than that of the eMBB service data (that is, the URLLC service data has high reliability requirements compared to the eMBB service data). Specifically, different types of services can be distinguished at the physical layer, for example, according to Downlink Control Information (DCI), Radio Network Temporary Identity (RNTI), Modulation and Coding Scheme. (MCS) table, SR period, transmission time length, etc., or Media Access Control (MAC) layer distinction, for example, according to the corresponding logical channel / logical channel group priority. It should be noted that the embodiment of the present invention does not limit the method for distinguishing service types, that is, the embodiment of the present invention does not limit other methods for distinguishing service types.

Optionally, in the embodiment of the present invention, the processing method is: when the SR is transmitted and the PUSCH is discarded, the transmission SR is transmitted on the PUCCH resource of the SR; the processing method is: when the PUSCH and the SR are transmitted, the SR is transmitted on the PUSCH (Can use the puncturing method or the rate matching method) for transmission. It should be noted that, for a method of transmitting SR on the PUSCH by using a puncturing method or a rate matching method, reference may be made to the specific description in the following embodiments, and details are not described herein.

Optionally, in a possible implementation manner of the embodiment of the present invention, the foregoing processing manner may further include: transmitting a PUSCH and discarding the SR. With reference to FIG. 2, as shown in FIG. 3, the foregoing step 201 may be specifically implemented by the following steps 201 a and 201 b.

Step 201a: When the time domain resources of the PUSCH and the time domain resources of the SR overlap, and when the time interval is greater than or equal to the first threshold, the UE determines that the processing mode is: transmitting the PUSCH and discarding the SR.

In the embodiment of the present invention, the PUSCH includes a BSR, which is used to request transmission resources of the second type of service data.

In the embodiment of the present invention, the time interval is a time interval between a first time and a second time, and the first time is the time when the second type of service data arrives or the physical downlink control channel where the uplink grant information (UL Grant) is located ( Physical Downlink Control Channel (PDCCH) end time, the second time is the time when the UE starts to send PUSCH, and the uplink grant information is used to indicate the transmission resources of the first type of service data.

Exemplarily, the first threshold may be N1 + d, where N1 is a value related to the UE capability defined in the existing NR protocol (the minimum time required for the PDCCH where the UE receives the UL grant to the corresponding PUSCH), and d is In order to reuse the extra time required for the BSR, for example, d = 1/2/3 OFDM symbols, d may be related to the subcarrier interval, that is, different subcarrier intervals correspond to different values.

It should be noted that, in the embodiment of the present invention, if the UE first receives the second type of service data and then receives the PDCCH where the uplink grant information is located, the first time is the end time of the PDCCH where the uplink grant information is located; if the UE First receive the PDCCH where the uplink grant information is located, and then the second type of service data arrives, then the first time is the time when the second type of service data arrives, that is, the first time is the time when the second type of service data arrives and the uplink grant The end time of the PDCCH where the information is located is the later one.

It can be understood that, in the embodiment of the present invention, when the time interval is greater than or equal to the first threshold, because the reliability requirements of the second type of service data are relatively high, the PUSCH allocated by the base station to the UE cannot satisfy the service of the second type of service data. It is required that the UE cannot transmit the second type of service data on the PUSCH, but at this time the UE has enough time to process the first type of service data and BSR, and the UE can transmit the PUSCH (the PUSCH includes the BSR) to request the second type from the base station Type of business data transmission resources.

Exemplarily, as shown in FIG. 4, the time domain resource of the SR configured by the UE is 2 OFDM symbols, and the period of the SR is 7 OFDM symbols. After the URLLC service data arrives, if the UE receives a PDCCH containing uplink grant information, the uplink grant information indicates that the time domain length of the PUSCH is 6 OFDM symbols, and the time domain resources of the PUSCH and the SR time domain resources overlap (that is, PUSCH and SR Conflict). The UE may determine that the time interval t1 between the end time (that is, the first time) of the PDCCH where the uplink grant information is located and the time when the UE starts to send the PUSCH (that is, the second time) is longer (for example, t1 is greater than the first threshold), and then the UE It can be determined that the processing mode is: transmitting the PUSCH and discarding the SR.

Step 201b: When the time domain resources of the PUSCH and the time domain resources of the SR overlap and the time interval is less than the first threshold, the UE determines that the processing mode is: transmitting the SR and discarding the PUSCH, or transmitting the PUSCH and the SR .

It can be understood that, in the embodiment of the present invention, when the time interval is less than the first threshold, because the time interval between the time when the second type of service data arrives and the time when the UE starts sending PUSCH is short, the UE does not have enough time. Cancel the preparation of the first type of service data and transmit the second type of service data and BSR on the PUSCH, but at this time the UE has enough time to cancel the PUSCH and prepare for the transmission of the SR. The UE can discard the PUSCH and transmit the SR to the base station. Request a transmission resource of the second type of service data.

It can be understood that, in the embodiment of the present invention, when the time interval is less than the first threshold, because the time interval between the time when the second type of service data arrives and the time when the UE starts sending PUSCH is short, the UE does not have enough time. Cancel the preparation of the first type of service data and transmit the second type of service data and BSR on the PUSCH, but at this time the UE has sufficient time to prepare the SR and PUSCH. The UE can transmit the PUSCH and transmit the SR on the PUSCH to the base station. Request a transmission resource of the second type of service data.

Exemplarily, as shown in FIG. 5, the time domain resource of the SR configured by the UE is 2 OFDM symbols, and the period of the SR is 7 OFDM symbols. When the UE receives a PDCCH containing uplink grant information, the uplink grant information indicates that the time domain length of the PUSCH is 9 OFDM symbols, and the time domain resources of the PUSCH and the SR time domain resources overlap. If the URLLC service data arrives after the UE receives the PDCCH containing uplink grant information, the UE can determine the time between the time when the URLLC service data arrives (that is, the first time) and the time when the UE starts sending the PUSCH (that is, the second time). The interval t2 is short (for example, t2 is less than the first threshold), and then the UE may determine that the processing mode is: transmitting the SR and discarding the PUSCH, or transmitting the PUSCH and the SR.

Optionally, in another possible implementation manner of the embodiment of the present invention, with reference to FIG. 2 and FIG. 6, the foregoing step 201 may be specifically implemented by the following step 201c.

Step 201c: In a case where the time domain resources of the PUSCH and the time domain resources of the SR overlap, and if the first condition is satisfied, the UE determines that the processing mode is: transmitting the SR and discarding the PUSCH.

In the embodiment of the present invention, the first condition may be any one of the following: a period of the SR is less than or equal to a second threshold, and a time domain length of the PUSCH is greater than or equal to N times a period of the SR, where N is greater than or equal to 2 Integer.

Optionally, in the embodiment of the present invention, the second threshold is defined by a protocol or configured by a high layer; N is defined by a protocol or configured by a high layer.

Exemplarily, the second threshold may be 7 OFDM symbols, or 1 slot, or M slots, and M is an integer greater than 1.

In the embodiment of the present invention, when the period of the SR is short (for example, the period of the SR is less than or equal to the second threshold), or the time domain length of the PUSCH is greater than or equal to N times the period of the SR, the UE transmits the SR, and Discarding the PUSCH can reduce the delay for the UE to send an SR request for uplink transmission resources, and meet the requirements of low latency and high reliability for the second type of service data.

Step 202: The UE processes PUSCH and SR according to a processing mode.

Optionally, in the embodiment of the present invention, the UE may transmit the PUSCH and discard the SR; or the UE may transmit the SR and discard the PUSCH; or the UE may transmit the PUSCH and the SR.

It can be understood that, in the embodiment of the present invention, after the UE sends a PUSCH to the base station, the base station may allocate the second type of service data transmission resources to the UE according to the BSR included in the PUSCH. Alternatively, after the UE sends the SR to the base station, the base station may allocate the second type of service data transmission resource to the UE according to the SR.

An embodiment of the present invention provides a method for processing PUSCH and SR. When the time domain resources of PUSCH and the time domain resources of SR overlap, the UE can determine the processing mode of PUSCH and SR (the processing mode is to transmit SR and discard PUSCH) Or transmit PUSCH and SR), and process the PUSCH and SR according to this processing method. Since the time domain resources of the PUSCH and the time domain resources of the SR overlap, the UE can process the PUSCH and SR according to the determined processing method of the PUSCH and SR, that is, the UE can transmit the SR and discard the PUSCH, or transmit the PUSCH and SR. Therefore, the conflict between the PUSCH and the SR can be solved, so that the UE can quickly request the transmission resources of the second type of service data from the base station, so that the UE can transmit the second type of service data, which can reduce the transmission delay of the UE.

Optionally, in the embodiment of the present invention, when the time interval is greater than or equal to the first threshold, the UE may transmit a PUSCH and discard the SR. Because the reliability requirements of the second type of service data are relatively high, and the UE has sufficient time to process the first type of service data and BSR, the UE discards the SR and transmits a PUSCH (the PUSCH includes the BSR). At the same time of the conflict, the BSR can quickly request the transmission resources of the second type of service data from the base station through the BSR, so that the UE can transmit the second type of service data, thereby reducing the transmission delay of the UE and transmitting the first service on the PUSCH. Type data to improve uplink throughput.

Optionally, in the embodiment of the present invention, when the time interval is less than the first threshold, the UE may transmit an SR and discard the PUSCH. Because the time interval between the time when the second type of service data arrives and the time when the UE starts to send PUSCH is short, the UE does not have enough time to cancel the preparation of the first type of service data and transmit the second type of service data on the PUSCH And BSR, but at this time the UE has enough time to cancel the PUSCH and prepare for the transmission of the SR. Therefore, the UE transmits the SR and discards the PUSCH. While resolving the conflict between the PUSCH and the SR, it can quickly request the second type of service from the base station through the SR. Data transmission resources, so that the UE transmits service data of the second type, thereby reducing transmission delay of the UE.

Optionally, in the embodiment of the present invention, when the time interval is less than the first threshold, the UE may transmit PUSCH and SR. Because the time interval between the time when the second type of service data arrives and the time when the UE starts to send PUSCH is short, the UE does not have enough time to cancel the preparation of the first type of service data and transmit the second type of service data on the PUSCH And BSR, but at this time the UE has enough time to prepare the SR, so the UE transmits the PUSCH, and punches the SR on the PUSCH. While resolving the conflict between the PUSCH and the SR, it can quickly request the second type of service from the base station through the SR. Data transmission resources, so that the UE transmits the second type of service data, thereby reducing the transmission delay of the UE, and transmitting the first type of service data on the PUSCH, which improves the uplink throughput.

Optionally, in a possible implementation manner of the embodiment of the present invention, the processing manner is: transmitting PUSCH and SR. With reference to FIG. 2, as shown in FIG. 7, the above step 202 may be specifically implemented through the following steps 202 a and 202 b.

Step 202a: When the number of bits of the SR is less than or equal to the third threshold, the UE transmits a PUSCH, and transmits the SR in a punctured manner on the PUSCH.

Optionally, in the embodiment of the present invention, the third threshold is a protocol definition or a high-level configuration.

Exemplarily, the third threshold may be Q bits, and Q is an integer greater than or equal to 2.

It should be noted that, in the embodiment of the present invention, service data and SR (specifically, bit information of the SR) may be mapped on a resource element (Resource Element, RE) of the PUSCH.

The above-mentioned punctuation method (Puncture) can be understood as follows: After mapping service data to multiple REs (denoted as RE1) of the PUSCH, when mapping the SR to the PUSCH, the SR can be mapped to a part of the RE1 RE (marked as RE2). Because the amount of data of the SR is usually small, the RE (ie, RE2) mapped by the SR and the RE (ie, RE1) mapped by the service data partially overlap (denoted as an overlapping RE), that is, the RE of the SR mapping is usually in the RE of the business data mapping a part of.

It can be understood that, in the above puncturing method, among all REs in the PUSCH, each RE in the overlapping REs carries the SR and service data, and the service data carried in each RE in the overlapping REs is covered by the SR carried in the RE. .

In the embodiment of the present invention, when the number of bits of the SR is small (for example, the number of bits of the SR is less than or equal to the third threshold), the UE transmits the SR in a puncturing manner on the PUSCH, which has less impact on the performance of the PUSCH.

Step 202b: When the number of bits of the SR is greater than the third threshold, the UE transmits a PUSCH, and transmits the SR in a rate matching manner on the PUSCH.

The above-mentioned rate matching method (Rate Match) can be understood as: dividing all REs in the PUSCH (excluding REs occupied by reference signals) into two parts, one part of the RE (recorded as RE3) is used to map service data, and the other part RE (recorded as RE4) is used to map SR, that is, service data and SR are orthogonal.

Therefore, the conflict between the PUSCH and the SR is resolved. At the same time, the SR can quickly request the transmission resources of the second type of service data from the base station through the SR, so that the UE can transmit the second type of service data, thereby reducing the transmission delay of the UE, and transmitting the first type of service data on the PUSCH, improving Upstream throughput.
