Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a data processing method and a terminal.
Background
In the prior art, when resources collide with data with different physical layer characteristics, one of the data is selected to perform data transmission. Take different Physical Uplink Shared Channels (PUSCHs) as examples, as shown in fig. 1a and 1 b. Referring to fig. 1a, a Dynamic Grant (DG) indicates a shorter PUSCH, and a Configured Grant (CG) indicates a longer PUSCH, and since the shorter PUSCH is to be preferentially transmitted, when two different PUSCHs collide in a time-frequency domain, the longer PUSCH data is dropped. Thus, the data of the configuration authority is lost in fig. 1 a. Referring to fig. 1b, the dynamic grant is a longer PUSCH, and the configured grant configures a shorter PUSCH, and when resources collide, the longer PUSCH, i.e., the dynamically granted data, is preferentially discarded.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises," "comprising," or any other variation thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means that at least one of the connected objects, such as a and/or B, means that three cases, a alone, B alone, and both a and B, exist.
In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In order to facilitate understanding of the embodiments of the present invention, the following technical points are described below:
first, a Physical Uplink Shared Channel (PUSCH) duration/Physical Downlink Shared Channel (PDSCH) duration:
in order to adapt to the delay of different services and the requirement of scheduling flexibility, the concept of flexibly configuring physical layer characteristics is introduced into the system of Fourth Generation mobile communication system (4G)/fifth Generation mobile communication system (5G).
Here, the physical layer characteristic may further refer to one or more of PUSCH/PDSCH length, Subcarrier Spacing (SCS) width, Cyclic Prefix (CP) length, carrier characteristic, and whether configuration grant is available.
Taking the physical layer characteristic as PUSCH/PDSCH as an example:
most of the service 1 is small packets, and if a long PUSCH/PDSCH is set, the data block scheduled each time will be large, which may result in low resource efficiency.
The time delay requirement of the service 2 is higher, if a shorter PUSCH/PDSCH is set, the feedback time delay is also reduced, so that the integral loopback time delay is reduced, and the service transmission time delay is reduced.
The service 3 data packet is large, if a short PUSCH/PDSCH is set, the network side can carry out scheduling for many times, and control channel resources are wasted;
therefore, different PUSCH/PDSCH lengths may be configured for different required traffic.
Similarly, the network side may also configure other different physical layer characteristics according to different service requirements, which is not described herein again.
Secondly, configuration authorization:
the configuration grant is a transmission mode for periodically allocating resources in advance for Uplink (UL) data introduced by a New Radio (NR). Configuring the authorization includes: two ways of configuring the Grant type 1(Configured Grant type 1) and configuring the Grant type 2(Configured Grant type 2).
A configuration grant type1 and a configuration grant type2, where the configuration grant 2 is the same as a Semi-Persistent Scheduling (SPS) working mechanism of Long Term Evolution (LTE).
In NR, some UL resources are preconfigured on the network side, which facilitates transmission of services with high Latency requirements (e.g., Ultra-Reliable and Low Latency Communications (URLLC)) or services with a relatively regular service format (e.g., Voice over Internet Protocol (VoIP) services) on the configured UL resources, and the packet size and the service interval of VoIP are relatively fixed.
The configuration authorization type1 and the configuration authorization type2 are two scheduling modes, the same point is that the base station can pre-allocate a periodic resource location, and the UE can send data according to the base station and the allocated resource location.
The difference points are that:
the Configured Grant Type1 is the contents of Radio Resource Control (RRC) Configured Resource location, Modulation and Coding Scheme (MCS), Radio Bearer (RB), Hybrid automatic repeat request (HARQ) number, cycle, and the like, and does not require physical layer activation and deactivation processes, and takes effect after RRC configuration, see fig. 2.
The Configured grant type2 is also the resource location, HARQ number, and period Configured by RRC, but not the RB and MCS configuration. Meanwhile, the physical layer needs to send Downlink Control Information (DCI) to activate and deactivate the resource, which is shown in fig. 3.
The HARQ ID values in the Configured Grant type1 and the Configured Grant type2 range from 0 to N-1. Wherein N is the number of HARQ processes scheduled for Configured Grant type1 and Configured Grant type2 Configured by RRC. It can be seen that the HARQ processes of the Configured Grant type1 and the Configured Grant type2 also include 0.
Embodiments of the present invention are described below with reference to the accompanying drawings. The data processing method and the terminal provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a fifth-generation mobile communication technology (5G) system, an Evolved Long Term Evolution (lte) system, or a subsequent Evolved communication system.

As shown in fig. 4, the wireless communication system may include: network Equipment 40 and a terminal (e.g., User Equipment (UE)), for example, denoted UE41, UE41 may communicate (transmit signaling or transmit data) with network Equipment 40. In practical applications, the connections between the above devices may be wireless connections, and fig. 4 illustrates solid lines for convenience and intuition of the connection relationships between the devices.

The user equipment provided by the embodiment of the invention can be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like.
Referring to fig. 5, an embodiment of the present invention provides a data processing method, where an execution subject of the method may be a terminal, and the method includes: step 501.
Step 501: under the condition that a first authorized first resource and a second authorized second resource collide, if a data packet of the first authorization is not packaged, a logic channel multiplexing process is executed before the processing delay of the first authorization is cut off; and/or, under the condition that a first authorized resource and a second authorized resource collide, if the data packet of the first authorization is already packaged, if new data arrives after the first data packet is packaged and before the deadline of the second data packet, executing a logical channel multiplexing process, judging the priority of the first authorization and the second authorization, and selecting the first authorization or the second authorization to execute data transmission according to the priority result.
For example, according to the latest priority multiplexing result, the priority of the logical channel to which the data of the first authorized bearer belongs is higher than the priority of the logical channel to which the data of the second authorized bearer belongs, and then the priority of the first authorized bearer is higher than the priority of the second authorized bearer.
If the priority of the first grant is higher than the priority of the second grant, the UE will generate data according to the first grant and send the data on the first grant. Otherwise, the UE generates data according to the second authorization and sends the data on the second resource.
In some embodiments, the method further comprises:
under the condition that a first authorized first resource and a second authorized second resource collide, if the data packet of the first authorization is not packaged, before the processing delay of the first authorization is cut off, a logical channel multiplexing process of first authorization bearing data is executed.

in the case of collision of a first authorized first resource and a second authorized second resource, if the first authorized data packet is already packaged, after the first data packet is packaged to a second data packet deadline, if new data arrives, a logical channel multiplexing process of second authorized bearer data is executed.
In some embodiments, after performing the logical channel multiplexing procedure, the method further comprises: and according to the result of the execution of the logical channel multiplexing process, grouping the data.
In some embodiments, the method further comprises: updating Buffer status (Buffer status) of the first grant and the second grant in performing logical channel multiplexing. That is, according to the bearer information of the data, the newly arrived data is delivered to the corresponding logical channel cache.
In some embodiments, the first granted HARQ process identity is the same as the second granted HARQ process identity or the first granted HARQ process identity is different from the second granted HARQ process identity.
In the embodiment of the invention, the packet loss rate can be reduced, and the system performance can be improved.
Referring to fig. 6, an embodiment of the present invention provides a data processing method, where an execution subject of the method may be a terminal, and the method includes: step 601 and step 602.
Step 601: determining information related to a first grant and a second grant in case a first resource of the first grant conflicts with a second resource of the second grant;
in some embodiments, in the case that a first resource of a first grant conflicts with a second resource of a second grant, and a logical channel priority to which data is carried on the first grant is the same as a logical channel priority to which data is carried on the second grant, information related to the first grant and the second grant is determined. Step 602: and selecting the first authorization or the second authorization to perform data transmission according to the information related to the first authorization and the second authorization.
In some embodiments, in step 602, when one or more of the predetermined determination conditions is yes, the first authorization or the second authorization is selected to perform data transmission;
wherein the predetermined judgment condition includes one or more of:
(1) whether a PUSCH duration on the first grant is less than a duration on the second grant;
(2) whether a Modulation Coding Scheme (MCS) on the first grant is less than an MCS on the second grant;
(3) whether a subcarrier spacing (SCS) on the first grant is greater than an SCS on the second grant;
(4) the first grant carries a first Buffer Status Report (BSR), and triggers whether the priority of a logical channel of the first BSR is higher than the priority of a logical channel carrying data on a second grant;
(5) and the second authorization carries a second BSR, and whether the priority of the logical channel carrying the data on the first authorization is higher than the priority of the logical channel triggering the second BSR or not is judged.
In some embodiments, the first authorized Hybrid automatic repeat request (HARQ) process identity is the same as the second authorized HARQ process identity, or the first authorized HARQ process identity is different from the second authorized HARQ process identity.
In the embodiment of the invention, the packet loss rate can be reduced, and the system performance can be improved.
The flow of the data processing method according to the embodiment of the present invention is described below with reference to the first embodiment, the second embodiment, and the third embodiment.
The first embodiment is as follows: and when the UE determines that the resource collision exists, executing a priority multiplexing process before the processing delay of the first authorization is cut off.
Step 1: at time t0, the UE is about to perform a generate first packet process.
Optionally:
the first method is as follows: the UE receives a dynamic Downlink Control Information (DCI) scheduling at time t0, that is, the UE is dynamically scheduled to send data, see fig. 7;
the second method comprises the following steps: the UE finds that new Data arrives at time t0, such as Packet Data Convergence Protocol (PDCP) Data or Radio Link Control (RLC) Data arrives, and the UE configures the configuration authorization resource.
And the UE determines to start generating a first data packet according to the first mode or the second mode, wherein the first data packet is sent by using the first resource. The first resource is scheduled by a first grant, i.e. the dynamic DCI in the first mode or the configuration granted resource in the second mode.
Step 2: when the UE generates the first packet, it finds that the first resource conflicts with the second resource, that is, the resources overlap, and then before the processing delay of the first grant expires, assuming that the time is t1, the UE performs the priority multiplexing process. The second resource is scheduled by a second grant, which may be a dynamic grant or a configuration grant.
Optionally, the UE generates a second data packet, and the second data packet is sent using the second resource.
The UE updates the buffer status, and at this time, the data status in the buffer is: buffer status (t0) -MAC PDU size in grant 1+ new arrival data.
Wherein buffer status (t0) represents: at time t0, the buffer status of the UE;
MAC PDU size in grant 1 indicates: a size of a data packet carried in the first grant;
new arrival data represents: new data size arrived during the time period t1-t 0.
And step 3: the UE compares the priority relationship of the first grant and the second grant.
Optionally, the UE determines priorities of the first grant and the second grant according to the latest priority multiplexing result, and selects the first grant or the second grant to perform data transmission according to the priority result. For example, according to the latest priority multiplexing result, the priority of the logical channel to which the data of the first authorized bearer belongs is higher than the priority of the logical channel to which the data of the second authorized bearer belongs, and then the priority of the first authorized bearer is higher than the priority of the second authorized bearer.
If the priority of the first grant is higher than the priority of the second grant, the UE will generate data according to the first grant and send the data on the first grant. Otherwise, the UE generates data according to the second authorization and sends the data on the second resource. Optionally, physical layer characteristics on the first grant and the second grant are compared, including PUSCH length, SCS width, MCS size, and the like.
Such as: and when the first authorized PUSCH is smaller than the second authorized PUSCH, judging that the priority of the first authorization is higher than that of the second authorization, generating data by the UE according to the first authorization and transmitting the data on the first resource, otherwise, generating the data by the UE according to the second authorization and transmitting the data on the second resource.
Such as: and when the SCS of the first authorization is larger than the SCS of the second authorization, judging that the priority of the first authorization is higher than that of the second authorization, generating data by the UE according to the first authorization and sending the data on the first resource, otherwise, generating the data by the UE according to the second authorization and sending the data on the second resource.
Such as: and when the MCS of the first authorization is lower than the MCS of the second authorization, judging that the priority of the first authorization is higher than that of the second authorization, generating data according to the first authorization by the UE, and sending the data on the first resource, otherwise, generating the data according to the second authorization by the UE, and sending the data on the second resource.
Example two: the UE performs a multiplexing procedure when data arrives.
Referring to fig. 8, the specific steps are as follows:
step 1: at time t 0', the UE has generated a first packet procedure
Step 2: after the UE generates the first packet, let it be t 0', if new data arrives, such as PDCP PDUs or RLC PDUs, to the buffer of the Medium Access Control (MAC) layer, the UE will perform a priority multiplexing procedure.
And step 3: the second grant is reached at time t1, and when the second resource indicated by the second grant conflicts with the first resource, the UE compares the priority relationship of the first grant and the second grant.
When the second data packet is generated, the data state in the cache at this time is:
buffer status(t0)–MAC PDU size in grant 1+new arrival data。
wherein buffer status (t0) represents: at time t0, the buffer status of the UE;
MAC PDU size in grant 1 indicates: a size of a data packet carried in the first grant;
new arrival data represents: new data size arriving during the time period t1-t 0'.
Optionally, the UE determines priorities of the first grant and the second grant according to the latest priority multiplexing result, and selects the first grant or the second grant to perform data transmission according to the priority result. For example, according to the latest priority multiplexing result, the priority of the logical channel to which the data of the first authorized bearer belongs is higher than the priority of the logical channel to which the data of the second authorized bearer belongs, and then the priority of the first authorized bearer is higher than the priority of the second authorized bearer.
If the priority of the first grant is higher than the priority of the second grant, the UE will generate data according to the first grant and send the data on the first grant. Otherwise, the UE generates data according to the second authorization and sends the data on the second resource.
Optionally, physical layer characteristics on the first grant and the second grant are compared, including PUSCH length, SCS width, MCS size, and the like.
Such as: and when the first authorized PUSCH is smaller than the second authorized PUSCH, the priority of the first authorization is considered to be higher than that of the second authorization, and the UE performs data transmission on the first resource, otherwise, the UE transmits the data on the second resource.
Such as: when the first authorized SCS is greater than the second authorized SCS, the priority of the first authorization is considered higher than the priority of the second authorization, and the UE will perform sending data on the first resource, otherwise, sending data on the second resource.
Such as: when the MCS of the first grant is lower than the MCS of the second grant, the priority of the first grant is considered to be higher than the priority of the second grant, and the UE performs data transmission on the first resource, otherwise, the UE transmits data on the second resource.
If the priorities of the first grant and the second grant are the same, according to the prior art, if the configuration grant and the dynamic grant collide, the data of the configuration grant is lost, but because the configuration grant may be configured to transmit data with higher requirement on delay, and the dynamic grant may be configured to data with lower requirement on delay, according to the prior art, the configuration grant is lost, and then the data with higher requirement on delay is lost, so that the problem needs to be solved.
Example three:
referring to fig. 9, the specific steps are as follows:
step 1: when data transmission is performed, if the first grant indicates that the first resource collides with, i.e., overlaps with, the second grant indicates that the second resource;
and the UE compares the logical channel information of the data loaded on the first resource and the second resource. The logical channel information may be logical channel priority information for acquiring data multiplexed on the first resource/the second resource.
Determining the comparison result: the priority of the first resource and the second resource is the same.
Step 2: the UE performs any one of the following modes:
the first method is as follows: physical characteristic information of the first grant and the second grant configuration is compared.
Such as: and comparing the PUSCH length, the SCS width, the MCS information and the like.
If the length of the PUSCH of the first authorization configuration is smaller than that of the PUSCH of the second authorization configuration;
and/or the SCS width of the first authorization configuration is larger than the PUSCH length of the second authorization configuration;
and/or whether the MCS of the first grant configuration is less than the MCS of the second configuration grant;
and/or whether the MCS of the first grant configuration can only use 64 Quadrature Amplitude Modulation (QAM) and cannot use 256 QAM;
and/or the first grant configures a repeat transmission;
and/or, the first grant carries a first BSR, and whether the priority of the logical channel triggering the first BSR is higher than the priority of the logical channel carrying data on the second grant;
and/or, the second grant carries a second BSR, and whether the priority of the logical channel carrying data on the first grant is higher than the priority of the logical channel triggering the second BSR.
In the embodiment of the present invention, the physical characteristic information configured by comparing the first authorization and the second authorization is not specifically limited.
If one or more of the above satisfies "yes", the UE will send the first data packet on the first resource, otherwise the UE sends the second data packet on the second resource.
The second method comprises the following steps: physical characteristic information of the first resource and the second resource is compared.
Such as: and comparing the PUSCH length, SCS width, MCS information and the like of the resources.
If the length of the PUSCH of the first resource is smaller than that of the PUSCH of the second resource;
and/or the SCS width of the first resource is larger than the PUSCH length of the second resource;
and/or whether the MCS of the first resource is less than the MCS of the second resource;
