Abstract

This disclosure relates to methods and devices for wireless communication resource configuration. Various schemes of configuration of sidelink control resources and/or sidelink data communication resources enable reduction of time duration that a user equipment is required to monitor sidelink communication resources for sidelink data, thereby providing power saving in sidelink communication.

Claims (46)

1. A method for controlling wireless sidelink communication, comprising:

determining, by a first user equipment (UE), a wireless resource configuration for specifying a first set of wireless resources for transmission of one or more sidelink control information in a sidelink resource period; and

transmitting, by the first UE, a sidelink control information of the one or more sidelink control information over one of the first set of wireless resources prior to a transmission of a set of sidelink data over one of a set of second wireless resources within the sidelink resource period, wherein

the set of second wireless resources are allocated for sidelink communication and comprises one or more sidelink-on durations within the sidelink resource period, and the first set of wireless resources correspond to one or more time points and to the one or more sidelink control information;

the sidelink control information is transmitted over a first radio carrier at a first time point of the one or more time points; and

the sidelink control information comprises wakeup indicators for indicating to a second UE whether or not to monitor other radio carriers for sidelink communications during a configured time period following the first time point.

2. The method of claim 1 , wherein:

the configured time period corresponds to a time between the time point and a next time point in the one or more time points.

3. The method of claim 1 , wherein the sidelink control information further comprises a wakeup indicator for indicating to the second UE whether or not to monitor the set of second wireless resources during a configured time period following a reception of the sidelink control information.

4. The method of claim 1 , wherein the wireless resource configuration comprises one or more resource time offsets specifying the one or more time points and the wireless resource configuration comprises at least one of:

a first identifier for the first set of wireless resources;

a second identifier for the wireless resource configuration;

a sidelink wakeup configuration for indicating to the second UE whether or not to monitor the set of second wireless resources allocated for sidelink communication following a time point of the one or more time points when no sidelink control information is detected at the time point;

a radio network temporary identifier (RNTI) value for scrambling cyclic redundancy check (CRC) of the one or more sidelink control information; or

a sidelink reference signal received power (SL-RSRP) report indicator for indicating to the second UE to transmit a periodic SL-RSRP report when a sidelink-on duration timer does not start.

5. The method of claim 1 , wherein the sidelink control information further comprises at least one of:

a destination identifier for identifying the set of sidelink data; or

an SCell dormancy indicator bitmap, where each bit of the bitmap corresponds to one of SCell groups configured by higher layers with the most significant bit to the least significant bit of the bitmap corresponding to the first to the last configured SCell groups.

6. The method of claim 1 , wherein the first UE obtains the wireless resource configuration from the second UE and the second UE obtains the wireless resource configuration from its serving cell.

7. The method of claim 1 , wherein:

the first UE and the second UE belongs to a group-cast UE group; and

the first UE receives the wireless resource configuration from a third UE of the group-cast UE group.

8. The method of claim 7 , wherein the first UE is configured to always monitor for sidelink data for at least one sidelink-on duration following its transmission of the sidelink control information.

9. The method of claim 7 , wherein the wireless resource configuration further comprises a group member indicator that identifies at least one group member of the group-cast UE group that always monitor sidelink data for at least one sidelink-on duration following their transmission of sidelink control information.

10. The method of claim 9 , wherein group member indicator comprises a bitmap or group member identifiers of the at least one group member of the group-cast UE group.

11. The method of claim 7 , wherein each UE in the group-cast UE group are associated with one of a set of wireless resource configurations for specifying non-conflicting timing for transmission of sidelink control information among the group-cast UE group.

12. Method of claim 7 , wherein the third UE obtains the wireless resource configuration from its serving cell, and before the third UE obtains the wireless resource configuration, the third UE is configured to send at least one of its sidelink UE information or sidelink UE information of the group-cast UE group to its serving cell for requesting the wireless resource configuration.

13. A method for controlling wireless sidelink communication, comprising:

determining, by a first user equipment (UE), a wireless resource configuration for specifying a first set of wireless resources for reception of one or more sidelink control information in a sidelink resource period;

monitoring, by the first UE, the first set of wireless resources for one or more sidelink control information from a second UE during the sidelink resource period; and

monitoring a set of second wireless resources for a set of sidelink data from the second UE for a configured time period within the sidelink resource period after receiving a sidelink control information of the one or more side link control information from the second UE, wherein

the set of second wireless resources is allocated for sidelink communication and comprises one or more sidelink-on durations within the sidelink resource period, and the first set of wireless resources correspond to one or more time points and to the one or more sidelink control information;

the sidelink control information is transmitted over a first radio carrier at a first time point of the one or more time points; and

the sidelink control information comprises wakeup indicators for indicating to the second UE whether or not to monitor other radio carriers for sidelink communications during the configured time period following the first time point.

14. The method of claim 13 , wherein:

the configured time period corresponds to a time between the time point and a next time point in the one or more time points.

15. The method of claim 13 , wherein the sidelink control information further comprises a wakeup indicator for indicating to the first UE whether or not to monitor the set of second wireless resources during a configured time period following a reception of the sidelink control information.

16. The method of claim 13 , wherein the wireless resource configuration comprises one or more resource time offsets specifying the one or more time points and the wireless resource configuration comprises at least one of:

a first identifier for the first set of wireless resources;

a second identifier for the wireless resource configuration;

a sidelink wakeup configuration for indicating to the first UE whether or not to monitor the set of second wireless resources allocated for sidelink communication following a time point of the one or more time points when no sidelink control information is detected at the time point;

a radio network temporary identifier (RNTI) value for scrambling cyclic redundancy check (CRC) of the one or more sidelink control information; or

a sidelink reference signal received power (SL-RSRP) report indicator for indicating to the second UE to transmit a periodic SL-RSRP report when a sidelink-on duration timer does not start.

17. The method of claim 13 , wherein the sidelink control information further comprises at least one of:

a destination identifier for identifying the set of sidelink data; or

an SCell dormancy indicator bitmap, where each bit of the bitmap corresponds to one of SCell groups configured by higher layers with the most significant bit to the least significant bit of the bitmap corresponding to the first to the last configured SCell groups.
