The present disclosure relates to the field of communications technology, and in particular to a method for receiving PDSCH, an apparatus for receiving PDSCH and a processor-readable storage medium.
With the increasing popularity of mobile video services, peer-to-peer multicast/broadcast streams, software upgrades through mobile networks, group communications, and broadcast/multicast Internet of Things applications, the global mobile communication industry has reached a consensus that the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G) networks need to have the ability to flexibly and dynamically allocate radio spectrum and network resources between unicast and multicast services, and need to support independent deployment for broadcast/multicast networks.

When describing the embodiments of the present disclosure, some concepts used in the following description are explained first.
In a time slot, in a case that there are multiple PDSCHs to be delivered, the UE needs to select and exclude PDSCHs according to UE capabilities and service priorities, so as to determine the type and quantity of PDSCHs finally received by the UE.
Different service data have different service priorities, such as: in Ultra-Reliable and Low Latency Communications (Ultra-Reliable and Low Latency Communications, URLLC), Multicast Control Channel (Multicast Control Channel, MCCH) PDSCH (MCCH-PDSCH), MBS and Enhanced Mobile Broadband (Enhanced Mobile Broadband, eMBB), URLLC>MCCH-PDSCH>MBS>eMBB service. When determining and receiving the PDSCH, service priority is a factor that must be considered. Generally, the UE will select to receive service data with higher priority. In the present disclosure, it is assumed that the service priority has been configured, that is, each scheduled data service PDSCH has a corresponding priority level, and the priority values are different.
The UE receiving capability is defined as the quantity of PDSCHs simultaneously received by the UE in a frequency-division multiplexing (Frequency-division multiplexing, FDM) or/and time-division multiplexing (Time-division multiplexing, TDM) mode within one time slot. Specific UE receiving capability determination parameters may include the following:
Specifically, an embodiment of the present disclosure provides a method for receiving PDSCH, which is used to solve the problem that the terminal cannot determine the received PDSCH when the scheduling of the PDSCH by the base station exceeds the receiving capability of the terminal.
As shown in
Step 101, determining, by a terminal, a receiving PDSCH set according to a priority of a candidate physical downlink shared channel PDSCH scheduled by a base station, where quantity of PDSCHs to be received in the receiving PDSCH set meets receiving capability of the terminal;
In this embodiment, the base station may schedule PDSCHs exceeding the receiving capability of the terminal in one time slot. For example, the maximum receiving capability of the terminal is N PDSCHs, and the quantity of PDSCHs scheduled by the base station is greater than N. The candidate PDSCH is the PDSCH scheduled by the base station in one time slot, and there may be multiple ones. The terminal determines the PDSCH to be received from the candidate PDSCH, that is, determines the PDSCH to be received. Specifically, the terminal may determine the PDSCH to be received according to the priority of each candidate PDSCH, wherein the priority of the candidate PDSCH may be protocol preconfiguration.
The receiving PDSCH set determined by the terminal may include multiple PDSCHs, and the quantity of PDSCHs meets the receiving capability of the terminal. The meeting the receiving capability of the terminal means that the quantity of PDSCHs in the receiving PDSCH set is less than or equal to the maximum receiving capability of the terminal.
Step 102, receiving, by the terminal, data on the PDSCH to be received in the receiving PDSCH set, and receiving, after the terminal determines the receiving PDSCH set, data on the PDSCH included in the receiving PDSCH set.
In the embodiment of the present disclosure, the terminal determines the receiving PDSCH set according to the priority of the candidate PDSCH scheduled by the base station, and the quantity of PDSCHs included in the receiving PDSCH set meets the receiving capability of the terminal, so that the terminal can receive multiple data services simultaneously, and may select the type and quantity of the finally received PDSCH according to the service priority to meet user requirements.
Further, the determining, by the terminal, the receiving PDSCH set according to the priority of the candidate PDSCH scheduled by the base station includes one of following:
It should be noted that, in this embodiment, when determining the PDSCH to be received in the receiving PDSCH set, the terminal selects the PDSCH with the highest priority in the current candidate PDSCH set each time. For example: the candidate PDSCH set includes 6 PDSCHs, and the terminal selects the PDSCH with the highest priority among the 6 PDSCHs as the PDSCH to be received for the first time, then the candidate PDSCH set at this time also includes 5 PDSCHs, in the second selection, the terminal selects the PDSCH with the highest priority among the five PDSCHs as the PDSCH to be received, and selects cyclically until the quantity of PDSCHs to be received meets the receiving capability of the terminal.
The method of determining the receiving PDSCH set is applicable to the Capability A and Capability B, that is, in a case that the receiving capability of the terminal is: in TDM mode, data of at most N PDSCHs is received, the PDSCH with the lowest priority shall be excluded in turn, until the quantity of PDSCHs in the candidate PDSCH set subjected to the exclusion process meets the receiving capability of the terminal; in a case that the receiving capability of the terminal is: in FDM mode, data of at most N PDSCHs is received, the PDSCH with the lowest priority shall be excluded in turn, until the quantity of PDSCHs in the candidate PDSCH set subjected to the exclusion process meets the receiving capability of the terminal.
It should be noted that, in this embodiment, when determining the PDSCH to be received in the receiving PDSCH set, the terminal selects the PDSCH with the lowest priority in the current candidate PDSCH set for exclusion each time. For example: the candidate PDSCH set includes 6 PDSCHs, and the terminal selects the PDSCH with the lowest priority among the 6 PDSCHs for the first time to exclude, then the candidate PDSCH set also includes 5 PDSCHs at this time, during the second selection, the terminal selects the PDSCH with the lowest priority among the five PDSCHs to exclude, and selects cyclically until the quantity of PDSCHs to be received meets the receiving capability of the terminal.
In this embodiment, the terminal receives the data on the PDSCHs in the TDM mode, or receives the data on the PDSCHs in the FDM mode, may start to select from the PDSCH with the highest priority in the candidate PDSCH set, until the quantity of selected PDSCHs meets the receiving capability of the terminal, or may start to exclude the PDSCH with the lowest priority in the candidate PDSCH set, until the quantity of PDSCHs in the candidate PDSCH set after PDSCH is excluded meets the receiving capability of the terminal.
The specific embodiments below respectively illustrate the specific method of determining the receiving PDSCH set according to PDSCH with the highest priority in the candidate PDSCH set, and the specific method of determining the receiving PDSCH set according to PDSCH with the lowest priority in the candidate PDSCH set.
Specifically, the determining the receiving PDSCH set according to the PDSCH with the highest priority in the candidate PDSCH set, may include:
In this embodiment, the UE selects the PDSCH with a higher priority from the candidate PDSCH set into the receiving PDSCH set, in a case that the total quantity of PDSCHs to be received in the receiving PDSCH set reaches the maximum receiving capability of the terminal, the operation of selecting the PDSCH to be received is stopped, and the PDSCH to be received in the receiving PDSCH set obtained at this time is the PDSCH of data to be received by the terminal.
In a case that the total quantity of PDSCHs to be received in the receiving PDSCH set does not reach the maximum receiving capability of the terminal, all PDSCHs in the candidate PDSCH set that overlap with the PDSCHs in the receiving PDSCH set in a time domain or frequency domain are excluded. After deleting the PDSCHs in the candidate PDSCH set that overlap with all the PDSCHs in the receiving PDSCH set in the time domain or frequency domain, the first candidate set is obtained, in a case that the first candidate set is an empty set, the operation of selecting the PDSCH to be received is stopped, and the PDSCH to be received in the receiving PDSCH set obtained at this time is the PDSCH of the data to be received by the terminal.
In a case that the first candidate set is not an empty set, then the first candidate set is used as the candidate PDSCH set, the step 1 is performed repeatedly, and the PDSCH with the highest priority is selected from the first candidate set into the receiving PDSCH set, the above operations are performed cyclically until the quantity of PDSCHs in the receiving PDSCH set meets the capability of the UE or the candidate PDSCH set is empty. The UE selects the data on the PDSCH in the receiving PDSCH set for reception.
It should be noted that, in this embodiment, in a case that the terminal receives data in TDM mode, the second PDSCH in the step 2 is a PDSCH overlapped in a time domain with all PDSCHs in the receiving PDSCH set; in a case that the terminal receives data in FDM mode, the second PDSCH in step 2 is a PDSCH overlapped in frequency domain with all PDSCHs in the receiving PDSCH set.
As an optional embodiment, the specific implementation process of this embodiment is described by taking the terminal receiving capability of TDM or FDM mode, and the terminal receiving at most N PDSCHs simultaneously as an example. In this embodiment, the terminal selects a PDSCH with a higher priority from the candidate PDSCH set for reception until the receiving capability of the UE is reached. In this embodiment, the type of the PDSCH may not be distinguished, for example, whether the PDSCH is a unicast PDSCH or an MBS PDSCH is not distinguished. And the priorities of different PDSCHs have been known, the specific steps are shown in
In this embodiment, the receiving PDSCH set is determined according to the PDSCH with the highest priority in the candidate PDSCH set, the quantity of PDSCHs to be received in the receiving PDSCH set meets the receiving capability of the terminal, the terminal can receive multiple data services simultaneously, and can select the quantity and type of PDSCHs finally received according to the service priority, which can meet the user requirements under the 5G network.
The above is the specific implementation process of determining the receiving PDSCH set according to the PDSCH with the highest priority in the candidate PDSCH set. The following describes the implementation process of determining the receiving PDSCH set according to PDSCH with the lowest priority in the candidate PDSCH set.
Specially, the excluding the PDSCH with the lowest priority in the candidate PDSCH set, and the determining the candidate PDSCH set subjected to the exclusion process as the receiving PDSCH set, may include:
In this embodiment, the UE excludes the PDSCHs with the low priority in the candidate PDSCH set, and then determines whether there is an overlapping between the PDSCHs in the second candidate set obtained after being updated, in a case that the quantity of PDSCHs in the second candidate set meets the receiving capability of the terminal, and there is no PDSCH overlapped in the time domain or frequency domain in the second candidate set, the second candidate set is determined as the receiving PDSCH set.
In a case that there is overlap between any two PDSCHs, the UE continues to exclude the PDSCHs with the low priority in the second candidate set, and performs the above-mentioned operations circularly until there is no that the remaining PDSCHs of the candidate PDSCH set overlap with each other. The UE selects the data on the PDSCH in the candidate PDSCH set for reception.
It should be noted that, in this embodiment, in a case that the terminal receives data in TDM mode, the “overlapped PDSCH” in the step 1 refers to: the PDSCH overlapped in a time domain; in a case that the terminal receives data in FDM mode, the “overlapped PDSCH” in the step 1 refers to: PDSCH overlapped in a frequency domain.
As an optional embodiment, the specific implementation process of this embodiment is described by taking the UE receiving capability of TDM or FDM mode, and the UE receiving at most N PDSCHs simultaneously as an example. In this embodiment, the UE sequentially excludes PDSCHs with the low priority from the candidate PDSCH set until the receiving capability of the UE is reached; then determines whether there is an overlapping in the candidate PDSCH set subjected to the exclusion process, and in a case that there is an overlapping, PDSCHs with the low priority continues to be excluded until there is no overlapping in the remaining candidate PDSCH sets. In this scheme, the service types of PDSCH are not distinguished, and the priority of PDSCH has been known, the specific steps are shown in
In a case that there is an overlapping in H_1 or the UE receiving capability is not met (that is, the quantity of PDSCHs in H_1 is greater than N), returning to execute step b), and continuing to remove the PDSCH with the lowest priority in H_1 until there is no overlapping or the receiving capability of the UE is met, executing step d).
In this embodiment, the PDSCH with the lowest priority in the candidate PDSCH set is excluded, and the receiving PDSCH set is determined, the quantity of PDSCHs to be received in the receiving PDSCH set meets the receiving capability of the terminal, the terminal can receive multiple data services simultaneously, and can select the quantity and types of PDSCHs finally received according to the service priority, which can meet the user requirements under the 5G network.
It should be noted that, according to the above-mentioned steps 1)-4) and steps a)˜d), after the receiving capability of the terminal is determined, the terminal may select a receiving PDSCH in one of the following schemes:
It is assumed that the receiving PDSCH set S_1={PDSCHx, PDSCHy, PDSCHz} obtained by scheme 1, and the receiving set H_1={PDSCHa, PDSCHb} obtained by scheme 2.
The judgment standard can be as follows:
Optionally, the method further includes: determining, in a case that two PDSCHs meet a first condition, that the two PDSCHs do not overlap in a time domain, where the first condition is: a start time of one of the two PDSCHs is later than an end time of the other PDSCH.
This embodiment is a method for determining that two PDSCHs do not overlap in the time domain. In a case that the start time of any one PDSCH is later than the end time of the other PDSCH, the two PDSCHs do not overlap in the time domain.
As an optional embodiment, relevant information of a time domain resource assignment table (Time Domain Resource Assignment table, TDRA table) may be used to determine whether there is an overlapping between two PDSCHs in a time slot. According to the TDRA table in the downlink control information (Downlink Control Information, DCI), the start symbol time slot position index number S of PDSCH, and the length L of continuous symbols allocated by PDSCH can be obtained. The end symbol time slot position index number m(m=S+L−1) of PDSCH can be obtained by calculating according to these two parameters.
In a case that the start symbol index number of any one PDSCH is greater than the end symbol index number of the other PDSCH, it means that the time domains do not overlap.
6 PDSCHs are taken as an example, the relationship between the 6 PDSCHs is shown in
For example: determining whether P1-PDSCH and P2-PDSCH overlap in a time domain:
Determining whether P1-PDSCH and P3-PDSCH overlap in the time domain:
Optionally, the method further includes: determining, in a case that the two PDSCHs meet a second condition, that the two PDSCHs do not overlap in a frequency domain, where the second condition is: a start resource block RB index number of one of the two PDSCHs is greater than an end RB index number of the other PDSCH.
This embodiment is a method for determining that two PDSCHs do not overlap in the frequency domain, in a case that the start RB index number of any one PDSCH is greater than the end RB index number of the other PDSCH, the two PDSCHs do not overlap in the frequency domain.
In a case that the frequency domains do not overlap is determined, the parameters in the frequency domain resource assignment field (Frequency domain resource assignment field) in DCI need to be used, such as start RB index number (RBstart) and configured continuous RB quantity (LRBs). The start symbol index number of any one PDSCH is greater than the end symbol index number of the other PDSCH and the two PDSCHs do not overlap in the frequency domain. The specific method is similar to the method for determining that two PDSCHs do not overlap in the time domain, and will not be repeated here.
It should be noted that a candidate PDSCH may be a PDSCH scheduled by the base station before receiving a target time threshold of a time slot. Optionally, the method further includes: receiving, in a case that the quantity of PDSCHs to be received does not meet maximum receiving capability of the terminal, data on PDSCH that do not overlap in the time domain or frequency domain, according to a time sequence of PDSCH scheduled by the base station after the target time threshold.
In this embodiment, due to the dynamic PDSCH scheduling, some PDSCHs are scheduled later, and the UE cannot determine whether there are other scheduled PDSCHs that need to be processed together subsequently when processing the PDSCH which start position reaches earlier. Therefore, the target time threshold can be set before receiving time slot, and the PDSCH scheduled before the target time threshold is preferentially processed. The target time threshold may be set at the first X symbols (symbols) of the current time slot (n), as shown in
The specific steps may be as follows:
In this embodiment, the target time threshold is set before receiving time slot, and the PDSCH scheduled before the target time threshold is used as the candidate PDSCH, and the terminal determines the receiving PDSCH set according to the priority of the candidate PDSCH; for the PDSCH scheduled after the target time threshold, the terminal selects and receives the PDSCH scheduled after the target time threshold according to the time sequence of the PDSCH. The UE may receive multiple data services simultaneously, and may select the quantity and type of PDSCHs finally received according to the service priority, which can meet the user requirements under the 5G network.
The implementation process of the terminal receiving PDSCH in the TDM mode and the implementation process of receiving PDSCH in the FDM mode are respectively described below through specific examples. 6 PDSCHs are taken as an example, the relationship between the 6 PDSCHs is shown in
Example 1: The terminal receives at most 3 PDSCHs simultaneously in TDM mode, and the terminal determines the receiving PDSCH set according to the PDSCH with the highest priority in the candidate PDSCH set, which specifically includes the following steps:
Step 3 (Step3): determining whether the receiving capability of the UE is met.
The UE receives S_1={P1-PDSCH, P2-PDSCH, P6-PDSCH}.
Example 2: the terminal receives at most 3 PDSCHs simultaneously in FDM mode, and the terminal determines the receiving PDSCH set according to the PDSCH with the highest priority in the candidate PDSCH set, which specifically includes the following steps:
Returning to Step 2: S_2′={P4-PDSCH}, S_1={P1-PDSCH, P2-PDSCH, P4-PDSCH}, S_2=0.
Step4: selecting, by the UE, PDSCHs in the receiving S_1 set.
The UE receives S_1={P1-PDSCH, P2-PDSCH, P4-PDSCH}.
Example 3: the terminal receives at most 3 PDSCHs simultaneously in TDM mode, and the terminal excludes the PDSCH with the lowest priority in the candidate PDSCH set, and determines the candidate PDSCH set subjected to the exclusion process as the receiving PDSCH set, which specifically includes the following steps:
Example 4: the terminal receives at most 3 PDSCHs simultaneously in FDM mode, and the terminal excludes the PDSCH with the lowest priority in the candidate PDSCH set, and determines the candidate PDSCH set subjected to the exclusion process as the receiving PDSCH set, which specifically includes the following steps:
According to the above-mentioned example 1, example 2, example 3, and example 4, the receiving PDSCH set obtained is shown in Table 2, where scheme 1 refers to: determining the receiving PDSCH set according to the PDSCH with the highest priority in the candidate PDSCH set; scheme 2 refers to: excluding PDSCH with a lowest priority in the candidate PDSCH set, and determining the candidate PDSCH set subjected to the exclusion process as the receiving PDSCH set.
According to the results of Scheme 1 and Scheme 2 in Table 2, when the UE receives multiple PDSCHs in TDM or FDM mode, if the terminal selects a scheme with a large receiving PDSCH set according to Criterion 1, then the UE selects receiving S_1; if the terminal selects a scheme with a large sum of priority weights according to Criterion 2, the UE selects receiving S_1.
In the embodiment of the present disclosure, the terminal determines the receiving PDSCH set according to the priority of the candidate PDSCH scheduled by the base station, and the quantity of PDSCHs included in the receiving PDSCH set meets the receiving capability of the terminal, so that the terminal can receive multiple data services simultaneously, and can select the type and quantity of the PDSCH received finally according to the service priority to meet user requirements.
