SYSTEM AND METHODS FOR SIGNALING MECHANISM FOR UE ASSISTANCE FEEDBACK
Some embodiments of this disclosure include apparatuses and methods for a signaling mechanism for user equipment (UE) assistance feedback in a wireless communication system. At least a radio frequency integrated circuit can be configured to receive a first configuration signal, and transmit a first message comprising a UE assistance feedback, generated based on the first configuration signal, in an uplink (UL) channel. The first message can contain an index of a profile with information on a service requirement, a traffic characteristic, or a combination thereof of a network. A processor, coupled to the radio frequency integrated circuit, can be configured to generate the UE assistance feedback based on the first configuration signal.
1 . A method comprising:
identifying, by a User Equipment (UE), a UE assistance information that includes UE preferences for two or more of a timeline parameter, a bandwidth part configuration, an antenna configuration, a discontinuous reception (DRX) configuration, a secondary cell (SCELL) or secondary cell group (SCG) activation/de-activation configuration, physical downlink control channel (PDCCH) parameters, or a number of carriers, for different traffic characteristics and power saving requirements of the UE;
generating a message comprising an indexed profile indicating the UE assistance information for each of the different traffic characteristics and power saving requirements; and
transmitting the message to a base station (BS) to indicate the UE assistance information.
2 . The method of claim 1 , wherein the antenna configuration includes one or more of a number of multiple input multiple output (MIMO) layers or antenna panel awareness information.
3 . The method of claim 1 , wherein the DRX configuration includes one or more of a preferred inactivity timer, on duration timer, or DRX cycle.
4 . The method of claim 1 , wherein the PDCCH parameters include one or more of PDCCH monitoring parameters, a search space configuration, or a maximum number of blind decoding candidates.
5 . The method of claim 1 , wherein the message is transmitted periodically or based on expiration of a timer.
6 . The method of claim 1 , further comprising receiving, by the UE, a request for the UE assistance information, wherein the message is transmitted responsive to the request.
7 . The method of claim 6 , wherein the request is included in a downlink control information (DCI) message intended for a group of UEs, wherein the request includes multiple fields, and wherein individual fields correspond to different UEs to indicate whether UE assistance information is triggered from a respective UE of the UEs.
8 . A non-transitory computer readable medium storing instructions that when performed by one or more processors of a User Equipment (UE), cause the UE to perform operations comprising:
identifying UE assistance information that includes UE preferences for two or more of a timeline parameter, a bandwidth part configuration, an antenna configuration, a discontinuous reception (DRX) configuration, a secondary cell (SCELL) or secondary cell group (SCG) activation/de-activation configuration, physical downlink control channel (PDCCH) parameters, or a number of carriers, for different traffic characteristics and power saving requirements of the UE;
generating a message comprising an indexed profile indicating the UE assistance information for each of the different traffic characteristics and power saving requirements; and
transmitting the message to a base station (BS) to indicate the UE assistance information.
9 . The non-transitory computer readable medium of claim 8 , wherein the antenna configuration includes one or more of a number of multiple input multiple output (MIMO) layers or antenna panel awareness information.
10 . The non-transitory computer readable medium of claim 8 , wherein the DRX configuration includes one or more of a preferred inactivity timer, on duration timer, or DRX cycle.
11 . The non-transitory computer readable medium of claim 8 , wherein the PDCCH parameters include one or more of PDCCH monitoring parameters, a search space configuration, or a maximum number of blind decoding candidates.
12 . The non-transitory computer readable medium of claim 8 , wherein the message is transmitted periodically or based on expiration of a timer.
13 . The non-transitory computer readable medium of claim 8 , wherein the operations further comprise receiving a request for the UE assistance information, wherein the message is transmitted responsive to the request.
14 . The non-transitory computer readable medium of claim 13 , wherein the request is included in a downlink control information (DCI) message intended for a group of UEs, wherein the request includes multiple fields, and wherein individual fields correspond to different UEs to indicate whether UE assistance information is triggered from a respective UE of the UEs.
15 . A User Equipment (UE) comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
identify UE assistance information that includes UE preferences for two or more of a timeline parameter, a bandwidth part configuration, an antenna configuration, a discontinuous reception (DRX) configuration, a secondary cell (SCELL) or secondary cell group (SCG) activation/de-activation configuration, physical downlink control channel (PDCCH) parameters, or a number of carriers, for different traffic characteristics and power saving requirements of the UE;
generate a message comprising an indexed profile indicating the UE assistance information for each of the different traffic characteristics and power saving requirements; and
transmit the message to a base station (BS) to indicate the UE assistance information,
wherein the one or more processors are further configured to receive a request for the UE assistance information, wherein the message is transmitted responsive to the request.
16 . The UE of claim 15 , wherein the antenna configuration includes one or more of a number of multiple input multiple output (MIMO) layers or antenna panel awareness information.
17 . The UE of claim 15 , wherein the DRX configuration includes one or more of a preferred inactivity timer, on duration timer, or DRX cycle.
18 . The UE of claim 15 wherein the PDCCH parameters include one or more of PDCCH monitoring parameters, a search space configuration, or a maximum number of blind decoding candidates. 3
19 . The UE of claim 15 , wherein the message is transmitted periodically or based on expiration of a timer.
20 . The UE of claim 15 , wherein the request is included in a downlink control information (DCI) message intended for a group of UEs, wherein the request includes multiple fields, and wherein individual fields correspond to different UEs to indicate whether UE assistance information is triggered from a respective UE of the UEs.
