Abstract

The subject application relates to method and apparatus of group-based resource allocation. A method performed by a first Base station (BS), comprises: transmitting a scheduling user equipment (S-UE) qualification criterion to a group of UEs; receiving at least one request for being a first S-UE from at least one member UE (M-UE) in the group that satisfies the S-UE qualification criterion; transmitting a signal indicating the first S-UE based on the at least one request; and transmitting, to the first S-UE, group-based resource information for the group of UEs.

First claim

What is claimed is:

1 . A base station for wireless communication, comprising:
at least one memory; and at least one processor coupled with the at least one memory and operable to cause the base station to:
transmit a scheduling user equipment (S-UE) qualification criterion to a group of UEs, wherein the S-UE qualification criterion comprises at least a threshold number of reachable member UEs (M-UEs);
receive at least one request for being a first S-UE from at least one M-UE in the group that satisfies the S-UE qualification criterion, wherein the request comprises at least a cell identity (ID) associated with the first S-UE;
transmit a signal indicating the first S-UE based on the at least one request; and
transmit, to the first S-UE, group-based resource information for the group of UEs.

2 . The base station of claim 1 , wherein the at least one processor is further operable to cause the base station to receive assistance information from the first S-UE.

3 . The base station of claim 2 , wherein the assistance information comprises at least one of: group information, traffic information, or member UE information.

4 . The base station of claim 1 , wherein the request further comprises at least one of: an M-UE identity (ID), a UE capability, reachable M-UE information, or corresponding coverage information.

5 . The base station of claim 1 , wherein to transmit the S-UE qualification criterion, the at least one processor is further operable to cause the base station to perform one or more of to broadcast the S-UE qualification criterion by system information block (SIB) signaling, or to transmit the S-UE qualification criterion by dedicated radio resource control (RRC) signaling.

6 . The base station of claim 1 , wherein the S-UE qualification criterion further comprises at least one of following parameters:
S-UE selection enable or disable indication; a threshold specified signal strength; or a threshold specified channel busy ratio (CBR).

7 . The base station of claim 1 , the first S-UE is configured as a single S-UE for the group of UEs.

8 . A user equipment (UE) for wireless communication, comprising:
at least one memory; and at least one processor coupled with the at least one memory and operable to cause the UE to:
receive a scheduling UE (S-UE) qualification criterion from a base station (BS), wherein the S-UE qualification criterion comprises at least a threshold number of reachable member UEs (M-UEs);
transmit a request to the BS to be an S-UE in response to the S-UE qualification criterion being satisfied, wherein the request comprises at least a cell identity (ID) associated with the S-UE; and
in response to being configured by the BS as the S-UE for a group of UEs:
broadcast an indication indicating the S-UE to one or more M-UEs in the group;
receive member UE information from the one or more M-UEs;
transmit assistance information including the member UE information to the BS;
receive group-based resource information from the BS; and
transmit the group-based resource information to the one or more M-UEs.

9 . The UE of claim 8 , wherein to transmit the request, the at least one processor is further operable to cause the UE to transmit the request using dedicated radio resource control (RRC) signaling.

10 . The UE of claim 8 , wherein the request comprises at least one of: an M-UE identity (ID), a UE capability, reachable M-UE information, or corresponding coverage information.

11 . The UE of claim 8 , wherein the assistance information comprises at least one of: group information or traffic information.

12 . The UE of claim 8 , wherein the at least one processor is further operable to cause the UE to specify to which M-UEs to report the member UE information.

13 . The UE of claim 8 , wherein a trigger to transmit the assistance information comprises one or more of:
if the UE is configured as the S-UE for the group; if the S-UE receives a scheduling request from an M-UE; if a size of the group goes beyond a first threshold; if a number of reachable M-UEs goes beyond a second threshold; if a traffic resource size of M-UEs goes beyond a third threshold; or if the S-UE moves from one cell to another cell.

14 . The UE of claim 8 , wherein the at least one processor is further operable to cause the UE to:
report reachable M-UE information to the BS for coordination with a different BS such that the UE is configured as a single S-UE for the group; and receive a coordination result from the BS.

15 . The UE of claim 14 , wherein the at least one processor is further operable to cause the UE to report the reachable M-UE information using dedicated radio resource control (RRC) signaling.

16 . A first user equipment (UE) for wireless communication, comprising:
at least one memory; and at least one processor coupled with the at least one memory and operable to cause the first UE to:
receive a first indicator indicating that a second UE in a group of UEs is a scheduling user equipment (S-UE), wherein the S-UE is one of at least a threshold number of reachable member UEs (M-UEs);
transmit member UE information to the S-UE, wherein the member UE information comprises at least a cell identity (ID) associated with the S-UE; and
receive group-based resource information from the S-UE.

17 . The first UE of claim 16 , wherein to transmit the member UE information, the at least one processor is further operable to cause the first UE to:
report member UE information using dedicated radio resource control (RRC) signaling; and initiate RRC connection with the S-UE after reporting the member UE information.

18 . The first UE of claim 16 , wherein the at least one processor is further operable to cause the first UE to:
receive a second indicator indicating a third UE as an S-UE; and select one of the second UE or the third UE as an S-UE.

19 . The first UE of claim 18 , wherein the at least one processor is further operable to cause the first UE to select one of the second UE or the third UE as an S-UE based at least in part on a signal strength of the second UE and the third UE.

20 . A method performed by a base station, the method comprising:
transmitting a scheduling user equipment (S-UE) qualification criterion to a group of UEs, wherein the S-UE qualification criterion comprises at least a threshold number of reachable member UEs (M-UEs); receiving at least one request for being a first S-UE from at least one M-UE in the group that satisfies the S-UE qualification criterion, wherein the request comprises at least a cell identity (ID) associated with the first S-UE; transmitting a signal indicating the first S-UE based on the at least one request; and transmitting, to the first S-UE, group-based resource information for the group of UEs.
