Abstract

The present disclosure provides a discontinuous reception scheduling method and device. The method includes: receiving, by a first user equipment (UE), m sets of DRX configuration information configured by a network side; wherein m is an integer greater than or equal to 1, and the m sets of DRX configuration information have a correspondence relationship including at least one of the following: the m sets of DRX configuration information correspond to different communication types; the m sets of DRX configuration information correspond to different service types; the m sets of DRX configuration information correspond to different scheduling modes; the m sets of DRX configuration information correspond to different frame types or data types of a service; the m sets of DRX configuration information correspond to different communication directions of a service or different services.

First claim

1 . A discontinuous reception (DRX) scheduling method, comprising:
receiving, by a first user equipment (UE), m sets of DRX configuration information configured by a network side; wherein m is an integer greater than or equal to 1, and the m sets of DRX configuration information have a correspondence relationship including at least one of the following:
the m sets of DRX configuration information correspond to different communication types;
the m sets of DRX configuration information correspond to different service types;
the m sets of DRX configuration information correspond to different scheduling modes;
the m sets of DRX configuration information correspond to different frame types or data types of a service;
the m sets of DRX configuration information correspond to different communication directions of a service or different services;
receiving and/or sending data, by the first UE, according to the m sets of DRX configuration information.

2 . The method according to claim 1 , wherein the receiving and/or sending data, by the first UE, according to the m sets of DRX configuration information, includes:
receiving and/or sending the data according to the m sets of DRX configuration information and association relationship between at least b sets of DRX configuration information in the m sets of DRX configuration information, wherein b is an integer greater than 1 and less than or equal to m; wherein the association relationship between the at least b sets of DRX configuration information is sent to the first UE by the network side through signaling, or is predefined, or is sent to a radio access layer of the first UE from a high layer of the first UE.

3 . The method according to claim 2 , wherein the association relationship between the at least b sets of DRX configuration information includes at least one of the following:
after receiving or sending data and/or signaling of a t-th service during an active time indicated by an i-th set of DRX configuration information in the m-sets of DRX configuration information, starting, after a specified time or immediately, an inactivity timer of a j-th set of DRX configuration information corresponding to a u-th service, and receiving and/or waiting to receive data and/or signaling of the u-th service; after receiving or sending data and/or signaling of a t-th service during an active time indicated by an i-th set of DRX configuration information in the m-sets of DRX configuration information, entering, after a specified time or immediately, an activity time of a j-th set of DRX configuration information corresponding to a u-th service, and receiving and/or waiting to receive data and/or signaling of the u-th service; after receiving or sending data and/or signaling of a t-th service during an active time indicated by an i-th set of DRX configuration information in the m-sets of DRX configuration information, starting, after a specified time or immediately, an on-duration timer of a j-th set of DRX configuration information corresponding to a u-th service, and receiving and/or waiting to receive data and/or signaling of the u-th service; after receiving or sending data and/or signaling of a t-th service during an active time indicated by an i-th set of DRX configuration information in the m-sets of DRX configuration of an associated u-th service, performing at least one of starting an inactive timer of a j-th set of DRX configuration information corresponding to the u-th service, starting an on-duration timer of the j-th set of DRX configuration information and entering an active time of the j-th set of DRX configuration information, and receiving and/or waiting to receive data and/or signaling of the u-th service; after receiving or sending a v-th type data and/or signaling of a q-th service during an active time indicated by an h-th set of DRX configuration information in the m sets of DRX configuration information, starting, after a specified time or immediately, an inactive timer of a z-th set of DRX configuration information corresponding to a u-th type data and/or signaling of the q-th service, and receiving and/or waiting to receive the u-th type data and/or signaling of the q-th service; after receiving or sending a v-th type data and/or signaling of a q-th service during an active time indicated by an h-th set of DRX configuration information in the m sets of DRX configuration information, entering, after a specified time or immediately, an active time of a z-th set of DRX configuration information corresponding to a u-th type of the q-th service, and receiving and/or waiting to receive the u-th type data and/or signaling of the q-th service; after receiving or sending a v-th type data and/or signaling of a q-th service during an active time indicated by an h-th set of DRX configuration information in the m sets of DRX configuration information, starting, after a specified time or immediately, an on-duration timer of a z-th set of DRX configuration information corresponding to a u-th type in the first service, and receiving and/or waiting to receive the u-th type data and/or signaling of the q-th service; after receiving or sending a v-th type data and/or signaling of a q-th service during an active time indicated by an h-th set of DRX configuration information in the m sets of DRX configuration information, according to service performance requirements including arrival characteristics and/or delay of a u-th type data of an associated q-th service, performing at least one of starting an inactive timer of a z-th set of DRX configuration information corresponding to the u-th type in the q-th service, starting on-duration timer of the z-th set of DRX configuration information and entering an active time of the z-th set of DRX configuration information, and receiving and/or waiting to receive the u-th type data and/or signaling in the q-th service.

5 . The method according to claim 2 , wherein when the m sets of DRX configuration information correspond to different communication types, the m sets of DRX configuration information include: a first set of DRX configuration information corresponding to a multicast mode, and a second set of DRX configuration information corresponding to a unicast mode;
the association relationship between the at least b sets of DRX configuration information includes: the first set of DRX configuration information is associated with the second set of DRX configuration information; wherein the receiving and/or sending the data according to the m sets of DRX configuration information and association relationship between at least b sets of DRX configuration information in the m sets of DRX configuration information, includes: receiving, by the first UE, new transmission data of a multicast service sent by a network device according to the first set of DRX configuration information; and, before receiving the new transmission data or during reception of the new transmission data, determining a reception mode of retransmission data, wherein the reception mode of the retransmission data includes: a multicast reception mode and/or a unicast reception mode; in case that the first UE fails to receive the new transmission data, according to the reception mode of the retransmission data, monitoring PDCCH scheduling signaling corresponding to the retransmission data and receives the retransmission data; when using the multicast reception mode, based on the first set of DRX configuration information, receiving retransmission data scrambled by group-radio network temporary identify (G-RNTI) and/or Group Configured Scheduling RNTI (G-CS-RNTI); when using the unicast reception mode, based on the second set of DRX configuration information, receiving retransmission data scrambled by C-RNTI and/or CS-RNTI; or, wherein the receiving and/or s
