Description

Configuration method and system for semi-static scheduling

technical field

The present invention relates to mobile communication technology, in particular to a semi-persistent scheduling (SPS) configuration method and system.

Background technique

Semi-Persistent Scheduling (SPS), also known as semi-persistent scheduling. Unlike dynamic scheduling, which allocates radio resources to UEs once per TTI (specified by PDCCH), SPS allows semi-static configuration of radio resources and periodically allocates the resources to a specific UE.

To put it simply, the eNodeB uses the PDCCH scrambled by the SPS C-RNTI at a certain TTI to designate the radio resource used by the UE, and the UE uses the SPS resource to receive or send data every time a cycle passes. The eNodeB does not need to issue the PDCCH in this subframe (ie, the SPS subframe) to specify the allocated resources.

Since the SPS has the feature of "once allocation, multiple use", it is not necessary to deliver DCI (including uplink or downlink DCI) to the UE at each TTI, thereby reducing the corresponding PDCCH overhead. The flexibility of SPS is slightly less, but the control signaling overhead is small, and it is suitable for the services with insignificant burst characteristics and guaranteed rate requirements.

In sidelink communication, in order to improve data transmission reliability and reduce transmission delay, the concept of carrier aggregation is introduced. For SPS services, different service types have different sets of available carriers. In addition, for highly reliable SPS services, it is necessary to duplicate two PDCP PDUs at the Packet Data Convergence Protocol (PDCP) layer, and send the two PDCP PDUs through two carriers respectively; or for SPS services with large data packets, it is necessary to The packets are separated and sent on different carriers. Therefore, there are scenarios in which different SPS service data packets are transmitted on different carriers.

The existing SPS configuration has multiple SPS interval (SPS interval) values, such as 20ms, 50ms, 100ms, 200ms, 300ms, 400ms, 800ms, 900ms, 1000ms, etc. It can be seen that the SPS configuration has more than 8 SPS intervals. However, the Radio Resource Control (RRC) of the existing system supports a maximum of 8 SPS configurations, and one configuration cannot contain all the SPS intervals. When the SPS service changes greatly and the existing SPS cycle cannot support it, the SPS configuration needs to be reconfigured and then activated, which will result in a large service transmission delay. On the other hand, in the R15 system, different service types correspond to different available carrier sets, and different service periods may vary greatly, and some service periods may be short (such as information sharing defined in the NR scenario), such as 20ms, or some The transmission period of some services is relatively large (regular software update, etc.), for example, 1000 ms, and the existing RRC configuration cannot configure the required SPS interval based on the carrier or the service type.

It can be seen that the existing SPS configuration method cannot meet the configuration requirements of the multi-carrier multi-SPS scheduling interval in the carrier aggregation scenario.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

The core idea of the present invention is to refine the SPS configuration granularity, and configure the SPS configuration set independently for each carrier, that is, for each carrier, configure the SPS configuration set dedicated to the carrier, so that the SPS scheduling interval covered by all the carriers is no longer Limited by the fact that RRC supports up to 8 SPS configurations, it can meet the configuration requirements of multi-carrier multi-SPS scheduling interval in the carrier aggregation scenario.

FIG. 1 is a schematic flowchart of a method according to an embodiment of the present invention. As shown in FIG. 1 , the configuration method for semi-static scheduling implemented by this embodiment mainly includes:

Step 101: When semi-persistent scheduling SPS configuration is required, send an RRC reconfiguration message to the user equipment UE, where the RRC reconfiguration message carries the SPS configuration set independently configured for each carrier.

In practical applications, various methods can be adopted, and the RRC reconfiguration message is used to send the SPS configuration set independently configured for each carrier to the UE. For example, the RRC reconfiguration message can use the following two methods to carry the SPS configuration set independently configured for each carrier:

Method 1: The RRC reconfiguration message uses the newly added semi-persistent scheduling configuration SPS-config field in the SL-InterFreqInfoListV2X information element, and carries an SPS configuration set independently configured for each carrier.

The SL-InterFreqInfoListV2X information element is an existing information element of the RRC reconfiguration message, and the information element is used to indicate the synchronization and resource allocation configuration of the adjacent frequency of V2X sidelink communication. The SL-InterFreqInfoListV2X information element is carried in SL-V2X-ConfigDedicated in the RRC reconfiguration message, or carried in SIB 21, supports independent SPS configuration on each carrier, and supports up to 8 SPS configurations on each carrier. Here, a new field is added to the information element, that is, a semi-persistent scheduling configuration (SPS-config) field, and the SPS-config field is used to carry an SPS configuration set independently configured for each carrier.

Preferably, in order to be compatible with the existing system, in the specific application, the SPS-config field can reuse the existing SPS configuration of the R14 system, and each SPS configuration contains at most 8 SPS configuration indexes (SPS-ConfigIndex), that is, , the SPS configuration set of each carrier contains no more than 8 SPS configurations.

The specific definition of SL-InterFreqInfoListV2X cell is as follows:

SL-InterFreqInfoListV2X information element

Method 2: The RRC reconfiguration message uses the newly added carrier-semi-persistent scheduling configuration ( Carrier-SPS-Config) field in the RadioResourceConfigDedicated information element to carry an SPS configuration set independently configured for each carrier.

Among them, the RadioResourceConfigDedicated information element is the existing information element of the RRC reconfiguration message of the existing system. Here, a new field is added to the information element, that is, the Carrier-SPS-Config field, which is carried by the Carrier-SPS- Config field as each A set of SPS configurations configured independently for each carrier, that is, configuring an SPS configuration, can configure a set of SPS configurations on one or more carriers.

The specific definition of the Carrier-SPS-Config field is as follows:

Wherein, SL-InterFreqInfoV2XIndex-r14 is the frequency index configured in SL-InterFreqInfoListV2X. Add the newly added Carrier-SPS-Config information element to the RadioResourceConfigDedicated information element, as follows:

The specific definition of the RadioResourceConfigDedicated cell is as follows:

RadioResourceConfigDedicated information element

Further, an SPS configuration set may be independently configured for each carrier according to a preset SPS configuration principle. Specifically, according to different application scenarios, the SPS configuration principles may include the following:

For PDCP repetition scenarios:

For a highly reliable SPS service, when two PDCP PDUs need to be duplicated at the Packet Data Convergence Protocol (PDCP) layer, and the two PDCP PDUs are sent through two carriers, the SPS service corresponding to two or more than two The SPS configuration sets of the carriers are configured to be the same or partially the same.

For data separation scenarios:

For the SPS service with large data packets, when the data packets need to be separated and sent through different carriers, the SPS configuration sets of two or more carriers corresponding to the SPS service are configured to be the same or partially the same.

For other scenarios:

According to the SPS service type corresponding to the carrier, according to the principle of configuring a small SPS interval for the short-period SPS service and a large SPS interval for the long-period SPS service, configure the SPS configuration set supported by each carrier.

Step 102, the UE performs corresponding SPS configuration according to the RRC reconfiguration message.

Specifically, after receiving the RRC reconfiguration message, the UE can use the following method to perform corresponding SPS configuration:

For each SPS configuration in the SPS configuration set indicated by the RRC reconfiguration message, if the index of the SPS configuration already exists in the locally saved SPS configuration set of the corresponding carrier, then according to the RRC reconfiguration message Instruct to update the corresponding SPS configuration saved locally, and keep the original activation state of the corresponding SPS configuration unchanged; otherwise, set the state of the SPS configuration to the deactivated state, and save the SPS configuration locally.

In the above method, for the SPS configuration that already exists locally in the UE, it is only necessary to update the content of the corresponding SPS configuration stored locally according to the SPS configuration carried in the currently received RRC reconfiguration message, and keep the SPS configuration in the The local state (ie activated or deactivated state) does not change.

The initial state of the newly configured SPS configuration is deactivated and needs to be activated through DCI. Therefore, in the above method, for the SPS configuration that does not exist locally in the UE, that is, the SPS configuration is newly added to the UE, then the When the SPS configuration carried in the currently received RRC reconfiguration message is saved locally, the state of the SPS configuration is set to a deactivated state.

Preferably, the performing corresponding SPS configuration includes:

If the RRC reconfiguration message carries information for indicating deletion of the SPS configuration, the UE deletes the corresponding SPS configuration from the locally stored SPS configuration set of the corresponding carrier.

That is, when the UE receives the SPS-ConfigSL-ToReleaseList-r14 in the SPS-Config of a certain carrier, it deletes the SPS configuration that is the same as the SPS-ConfigIndex-r14 carried by the SPS-ConfigSL-ToReleaseList-r14 in the carrier configuration.

Further, after using the RRC reconfiguration message to configure the SPS configuration set of each carrier, the existing DCI format 5A can be reused to activate or deactivate the SPS configuration on a certain carrier, specifically:

When it is necessary to notify the UE to activate or deactivate a carrier, send downlink control information DCI to the UE, the DCI is scrambled by the SL-SPS-V-RNTI of the UE, and the carrier indication (Carrier indicator) information is used to indicate the carrier index configured in SL-InterFreqInfoV2X, and the secondary link semi-persistent scheduling configuration index (SL SPS configuration index) information in the DCI is used to indicate the SPS scheduling interval (SPSinterval) index configured in the corresponding carrier , the activation/deactivation indication (Activation/release indication) information in the DCI is used to indicate the activation or deactivation of an SPS configuration corresponding to the carrier indicator information;

The UE performs activation or deactivation of the SPS configuration of the corresponding carrier according to the received DCI.

It should be noted here that, similar to in LTE, UEs configured with carrier aggregation (CA) use the same C-RNTI on all serving cells. Therefore, in eV2X sidelink communication, UEs configured with CA use the same C-RNTI on all carriers. on the same SL Semi-Persistent Scheduling V-RNTI.

It can be seen from the above method embodiments that the semi-persistent scheduling configuration method and system proposed by the embodiments of the present invention configure the SPS configuration set for each carrier separately, and use the RRC reconfiguration message to notify the SPS configuration set of each carrier. For the UE, the SPS configurations supported by all carriers are no longer limited to the 8 SPS configurations of the system. The SPS configuration set of each carrier can be configured with different SPS scheduling intervals with large differences according to the needs of the corresponding services, so as to meet the needs of the carrier It is required for the configuration of the multi-carrier multi-SPS scheduling interval in the aggregation scenario.
