Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer and more obvious, the present disclosure is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the disclosure and are not intended to limit the disclosure.
First embodiment
For a better understanding of the disclosed embodiments, the following brief description of semi-static scheduling and dynamic scheduling is provided:
the most different between semi-static scheduling and dynamic scheduling is: dynamic scheduling transmits DL (Downlink Control Information) or UL (Uplink) DCI to a UE (User Equipment/terminal) on a scheduling subframe, thereby scheduling a PDSCH or a PUSCH of a current subframe. The semi-persistent scheduling has a characteristic of "one-time allocation and multiple-time use", the base station allocates a time domain resource (i.e., a subframe) to a user through a UE-specific RRC (radio resource Control) signaling, the semi-persistent scheduling time domain resource is configured semi-statically, and the frequency domain resource and transmission information such as MCS (Modulation and Coding Scheme) are indicated in the active DCI. When the base station wants to enable the UE to receive or transmit the SPS PDSCH or the SPSPUSCH, the base station transmits DCI activating semi-static scheduling, and once the UE receives the DCI activating semi-static scheduling, the UE transmits or receives SPS service on a semi-static configured subframe; when the base station does not want the UE to continue sending or receiving the SPS service, the base station sends DCI (Physical Downlink Control Channel) for deactivating the semi-persistent scheduling in a PDCCH (Physical Downlink Control Channel), and when the UE receives the DCI for deactivating the semi-persistent scheduling, the base station stops sending or receiving the SPS service on a semi-persistent configured subframe. It should be noted that the dynamic scheduling DCI is scrambled by using C-RNTI (Cell Radio Network temporary identifier), and the activation/deactivation semi-persistent scheduling DCI is scrambled by using SPS C-RNTI.
For the same UE, the SPS service and the dynamic scheduling service cannot occur in the same subframe, if the UE blindly detects the DCI for dynamic scheduling by using the C-RNTI and the DCI for activating semi-persistent scheduling by using the SPS C-RNTI in a certain subframe, the UE follows the dynamic scheduling, but abandons the SPS transmission of the current subframe, wastes time-frequency resources, influences user experience and negatively influences user services.
As shown in fig. 1, a first embodiment of the present disclosure provides a method for transmitting a traffic channel, where the method includes:
step S11: and when the dynamic scheduling channel and the semi-persistent scheduling SPS channel are transmitted in the same time slot, determining the overlapping degree of the time-frequency resources of the dynamic scheduling channel and the SPS channel.
In this embodiment, the overlapping degree of the time-frequency resources of the dynamic scheduling channel and the SPS channel includes: the time frequency resources of the dynamic scheduling channel and the SPS channel are not overlapped, and the time frequency resources of the dynamic scheduling channel and the SPS channel are overlapped.
Under the condition that the time frequency resources of the dynamic scheduling channel and the SPS channel are overlapped, the overlapped time frequency resources can be divided into two situations which are smaller than a threshold value and larger than or equal to the threshold value.
The threshold is the number of REs (Resource elements, Resource blocks), and the threshold needs to consider a normal code rate range, so that two kinds of transmission can be performed through rate matching; meanwhile, considering the service model of a specific scene and the transmission data volume; when the threshold value is specifically realized, a certain setting range is provided so as to match different application conditions and scenes.
In this embodiment, whether the time-frequency resources of the dynamic scheduling channel and the SPS channel are overlapped or not may be determined according to whether the same RE or a part of REs is occupied by the PDSCH/PUSCH dynamically scheduled and the SPS PDSCH/PUSCH on the PDSCH/PUSCH channel or not.
In one embodiment, the determining the degree of overlap of the time-frequency resources of the dynamic scheduling channel and the SPS channel further comprises:
determining whether the dynamic scheduling channel and the SPS channel are transmitted in the same time slot.
Specifically, the SPS function may be enabled by the LTE network management system, at this time, two transmission types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH exist for a part of users of the base station cell at the same time, and two transmission types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH exist for a certain proportion of the same slot (slot) of the same user at the same time.
Step S12: and processing the transmission of the dynamic scheduling channel and the SPS channel according to the overlapping degree of the time-frequency resources of the dynamic scheduling channel and the SPS channel.
In one embodiment, the processing the transmissions of the dynamic scheduling channel and the SPS channel according to the degree of overlapping of the time-frequency resources of the dynamic scheduling channel and the SPS channel includes:
and under the condition that the time-frequency resources of the dynamic scheduling channel and the SPS channel are not overlapped, or under the condition that the time-frequency resources of the dynamic scheduling channel and the SPS channel are overlapped and the overlapped time-frequency resources are smaller than a threshold value, simultaneously transmitting the dynamic scheduling channel and the SPS channel.
In this embodiment, the dynamic scheduling channel and the SPS channel are transmitted simultaneously, and no traffic is dropped.
In this embodiment, said simultaneously transmitting said dynamically scheduled channel and said SPS channel further comprises:
rate matching the SPS channel.
In this embodiment, the rate matching is performed on the SPS channel, so that it is ensured that the dynamic scheduling channel and the SPS channel are normally transmitted.
In another embodiment, the determining the degree of overlap of the time-frequency resources of the dynamic scheduling channel and the SPS channel further comprises:
determining the service types and the priorities of the dynamic scheduling channel and the SPS channel;
the processing the transmission of the dynamic scheduling channel and the SPS channel according to the overlapping degree of the time-frequency resources of the dynamic scheduling channel and the SPS channel includes:
and under the condition that the time-frequency resources of the dynamic scheduling channel and the SPS channel are overlapped and the overlapped time-frequency resources are not less than a threshold value, processing the transmission of the dynamic scheduling channel and the SPS channel according to the priority of the service types of the dynamic scheduling channel and the SPS channel.
In this embodiment, the determining the traffic types of the dynamic scheduling channel and the SPS channel includes:
and determining the service types of the dynamic scheduling channel and the SPS channel according to the user terminal grade or the user behavior information.
For example, after determining that two transmission types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH exist in the same slot of the same user at the same time, the base station determines the service types to which the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH transmitted in the same slot of the user belong through information such as the user terminal level or the user behavior. For example, the dynamic scheduling channel for transmission is an embb (enhanced Mobile Broadband) service, and the SPS channel is an urrllc (Ultra Reliable & Low Latency Communication, Low Latency, high reliability Communication) service; or the transmitted dynamic scheduling channel is the uRLLC service, and the SPS channel is the eMB service.
In this embodiment, the processing the transmissions of the dynamic scheduling channel and the SPS channel according to the priority of the traffic types of the dynamic scheduling channel and the SPS channel includes:
channel transmissions of low priority traffic types are dropped.
In the above example, it is assumed that the transmitted dynamic scheduling channel is an eMMB service, the SPS channel is a uRLLC service, the uRLLC service is a high priority service, and the eMMB service is a low priority service. Therefore, eMMB traffic may be dropped and only uRLLC traffic is transmitted.
To better illustrate the embodiment, the following describes the transmission process of the traffic channel for different application scenarios with reference to fig. 2 to 4:
1) no overlap of time-frequency resources
As shown in fig. 2, step S201: it is determined whether the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH are transmitted in the same time slot.
Specifically, in the process of starting operation, the SPS function may be enabled through the LTE network management system, at this time, two transmission types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH exist for part of users of the base station cell at the same time, and two transmission types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH exist for the same slot (slot) of the same user in a certain proportion at the same time.
Step S202: and determining the service types of the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the dynamic scheduling process under the condition that whether the PDSCH/PUSCH and the SPS PDSCH/PUSCH are transmitted in the same time slot or not.
Specifically, after determining that two transmission types of a dynamically scheduled PDSCH/PUSCH and an SPS PDSCH/PUSCH exist in the same slot of the same user at the same time in a certain proportion, the base station confirms the service types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH transmitted in the same slot of the user through information such as the user terminal level or user behavior. For example, the transmitted PDSCH/PUSCH is eMB service, and the SPS PDSCH/PUSCH is uRLLC service; or the transmitted PDSCH/PUSCH is dynamically scheduled into uRLLC service, and the SPS PDSCH/PUSCH is eMB service.
Step S203: priorities of dynamically scheduled PDSCH/PUSCH and SPS PDSCH/PUSCH are determined.
And the base station determines the priority of the two transmission types according to the service types of the PDSCH/PUSCH and the SPS PDSCH/PUSCH which are dynamically scheduled. The high priority traffic type may be assigned priority 1 and the low priority traffic type may be assigned priority 2.
Step S204: and determining whether the time-frequency resources of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH are overlapped.
According to the specific situation of time-frequency resources occupied by the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the PDSCH/PUSCH channel by dynamic scheduling, whether resource blocks allocated by the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the PDSCH/PUSCH channel by dynamic scheduling have overlapping situation is determined, namely whether the same RE or part of REs are occupied by the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the PDSCH/PUSCH channel by dynamic scheduling at the same time.
Step S205: and under the condition that the time-frequency resources of the PDSCH/PUSCH and the SPS PDSCH/PUSCH are dynamically scheduled to be not overlapped, the time-frequency resources of the PDSCH/PUSCH and the SPS PDSCH/PUSCH are dynamically scheduled to be transmitted simultaneously.
Specifically, the PDSCH/PUSCH dynamically scheduled and the SPS PDSCH/PUSCH do not overlap in all time-frequency resources in the PDSCH/PUSCH channel, that is, no RE is occupied by the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH at the same time. And dynamically scheduling the PDSCH/PUSCH and the SPS PDSCH/PUSCH to be transmitted according to a normal operation flow and received by the terminal.
2) The time frequency resources are overlapped and the overlapped time frequency resources are more than or equal to a threshold value A
As shown in fig. 3, step S301: it is determined whether the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH are transmitted in the same time slot.
Specifically, in the process of starting operation, the SPS function may be enabled through the LTE network management system, at this time, two transmission types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH exist for part of users of the base station cell at the same time, and two transmission types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH exist for the same slot (slot) of the same user in a certain proportion at the same time.
Step S302: and determining the service types of the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the dynamic scheduling process under the condition that whether the PDSCH/PUSCH and the SPS PDSCH/PUSCH are transmitted in the same time slot or not.
Specifically, after determining that two transmission types of a dynamically scheduled PDSCH/PUSCH and an SPS PDSCH/PUSCH exist in the same slot of the same user at the same time in a certain proportion, the base station confirms the service types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH transmitted in the same slot of the user through information such as the user terminal level or user behavior. For example, the transmitted PDSCH/PUSCH is eMB service, and the SPS PDSCH/PUSCH is uRLLC service; or the transmitted PDSCH/PUSCH is dynamically scheduled into uRLLC service, and the SPS PDSCH/PUSCH is eMB service.
Step S303: priorities of dynamically scheduled PDSCH/PUSCH and SPS PDSCH/PUSCH are determined.
And the base station determines the priority of the two transmission types according to the service types of the PDSCH/PUSCH and the SPS PDSCH/PUSCH which are dynamically scheduled. The high priority traffic type may be assigned priority 1 and the low priority traffic type may be assigned priority 2.
Step S304: and determining whether the time-frequency resources of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH are overlapped.
According to the specific situation of time-frequency resources occupied by the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the PDSCH/PUSCH channel by dynamic scheduling, whether resource blocks allocated by the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the PDSCH/PUSCH channel by dynamic scheduling have overlapping situation is determined, namely whether the same RE or part of REs are occupied by the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the PDSCH/PUSCH channel by dynamic scheduling at the same time.
Step S305: and under the condition that the time-frequency resources of the PDSCH/PUSCH and the SPS PDSCH/PUSCH are dynamically scheduled to be overlapped and the overlap is not less than a threshold value A, discarding the transmission of the low-priority channel.
Specifically, the PDSCH/PUSCH and the SPS PDSCH/PUSCH are dynamically scheduled in all time frequency resources in the PDSCH/PUSCH channel, the overlapped time frequency resources are more than or equal to a threshold value A, the transmission data related to the SPS PDSCH/PUSCH is discarded (the service type of the SPS PDSCH/PUSCH is assumed to be low priority), and the PDSCH/PUSCH is dynamically scheduled to be normally transmitted.
3) The time frequency resources are overlapped and the overlapped time frequency resources are less than a threshold value A
As shown in fig. 4, step S401: it is determined whether the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH are transmitted in the same time slot.
Specifically, in the process of starting operation, the SPS function may be enabled through the LTE network management system, at this time, two transmission types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH exist for part of users of the base station cell at the same time, and two transmission types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH exist for the same slot (slot) of the same user in a certain proportion at the same time.
Step S402: and determining the service types of the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the dynamic scheduling process under the condition that whether the PDSCH/PUSCH and the SPS PDSCH/PUSCH are transmitted in the same time slot or not.
Specifically, after determining that two transmission types of a dynamically scheduled PDSCH/PUSCH and an SPS PDSCH/PUSCH exist in the same slot of the same user at the same time in a certain proportion, the base station confirms the service types of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH transmitted in the same slot of the user through information such as the user terminal level or user behavior. For example, the transmitted PDSCH/PUSCH is eMB service, and the SPS PDSCH/PUSCH is uRLLC service; or the transmitted PDSCH/PUSCH is dynamically scheduled into uRLLC service, and the SPS PDSCH/PUSCH is eMB service.
Step S403: priorities of dynamically scheduled PDSCH/PUSCH and SPS PDSCH/PUSCH are determined.
And the base station determines the priority of the two transmission types according to the service types of the PDSCH/PUSCH and the SPS PDSCH/PUSCH which are dynamically scheduled. The high priority traffic type may be assigned priority 1 and the low priority traffic type may be assigned priority 2.
Step S404: and determining whether the time-frequency resources of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH are overlapped.
According to the specific situation of time-frequency resources occupied by the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the PDSCH/PUSCH channel by dynamic scheduling, whether resource blocks allocated by the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the PDSCH/PUSCH channel by dynamic scheduling have overlapping situation is determined, namely whether the same RE or part of REs are occupied by the PDSCH/PUSCH and the SPS PDSCH/PUSCH in the PDSCH/PUSCH channel by dynamic scheduling at the same time.
Step S405: and under the condition that the time frequency resources of the PDSCH/PUSCH and the SPS PDSCH/PUSCH which are dynamically scheduled are overlapped and the overlap is less than a threshold value A, the time frequency resources of the PDSCH/PUSCH and the SPS PDSCH/PUSCH are dynamically scheduled to be transmitted simultaneously.
Specifically, the PDSCH/PUSCH and the SPS PDSCH/PUSCH are dynamically scheduled in all time-frequency resources in the PDSCH/PUSCH channel, the overlapped time-frequency resources are smaller than a threshold value A, related rate matching is carried out on the SPS PDSCH/PUSCH, and the fact that two kinds of transmission of the dynamically scheduled PDSCH/PUSCH and the SPS PDSCH/PUSCH are normally carried out is guaranteed.
