CHANNEL STATE INFORMATION REPORT SCHEDULING
Apparatuses, methods, and systems are disclosed for channel state information report scheduling. One method ( 800 ) includes receiving ( 802 ) a channel state information request at a first time. The method ( 800 ) includes determining ( 804 ) whether a resource for transmitting a channel state information report is available prior to a second time. The method ( 800 ) includes, in response to determining that no resource for transmitting the channel state information report is available prior to the second time, triggering ( 806 ) a scheduling request to request a new resource for transmitting the channel state information report prior to the second time.
1 . A method comprising:
receiving a channel state information request at a first time;
determining whether a resource for transmitting a channel state information report is available prior to a second time; and
in response to determining that no resource for transmitting the channel state information report is available prior to the second time, triggering a scheduling request to request a new resource for transmitting the channel state information report prior to the second time.
2 . The method of claim 1 , wherein the channel state information report is transmitted using a medium access control control element.
3 . The method of claim 1 , further comprising transmitting the scheduling request to request the new resource for transmitting the channel state information report prior to the second time.
4 . The method of claim 1 , wherein the new resource comprises a sidelink shared channel resource.
5 . The method of claim 1 , wherein determining that no resource for transmitting the channel state information report is available prior to the second time comprises determining that there are no sidelink shared channel resources allocated for accommodating a sidelink channel state information reporting medium access control control element and a subheader corresponding to the medium access control control element.
6 . The method of claim 1 , further comprising identifying a maximum time to respond to the channel state information request.
7 . The method of claim 6 , wherein the second time occurs the maximum time after the first time.
8 . The method of claim 1 , wherein the second time comprises a time of a next physical uplink control channel transmission occasion of a scheduling resource configuration for sidelink channel state information, and sidelink resources are allocated for a new transmission later than the second time.
9 . The method of claim 1 , further comprising, in response to determining that a resource for transmitting the channel state information report, the medium access control control element, or the combination thereof is available prior to the second time, triggering a scheduling request to request a new resource for transmitting the channel state information report, the medium access control control element, or the combination thereof in response to a sidelink logical channel restriction parameter.
10 . The method of claim 1 , wherein the sidelink restriction parameter comprises a PC5 logical channel restriction parameter.
11 . An apparatus comprising:
a receiver that receives a channel state information request at a first time; and
a processor that:
determines whether a resource for transmitting a channel state information report is available prior to a second time; and
in response to determining that no resource for transmitting the channel state information report is available prior to the second time, triggers a scheduling request to request a new resource for transmitting the channel state information report prior to the second time.
12 . The apparatus of claim 11 , wherein the channel state information report is transmitted using a medium access control control element.
13 . The apparatus of claim 11 , further comprising a transmitter that transmits the scheduling request to request the new resource for transmitting the channel state information report prior to the second time.
14 . The apparatus of claim 11 , wherein the new resource comprises a sidelink shared channel resource.
15 . The apparatus of claim 11 , wherein the processor determining that no resource for transmitting the channel state information report is available prior to the second time comprises the processor determining that there are no sidelink shared channel resources allocated for accommodating a sidelink channel state information reporting medium access control control element and a subheader corresponding to the medium access control control element.
16 . The apparatus of claim 11 , wherein the processor identifies a maximum time to respond to the channel state information request.
17 . The apparatus of claim 16 , wherein the second time occurs the maximum time after the first time.
18 . The apparatus of claim 11 , wherein the second time comprises a time of a next physical uplink control channel transmission occasion of a scheduling resource configuration for sidelink channel state information, and sidelink resources are allocated for a new transmission later than the second time.
19 . The apparatus of claim 11 , wherein the processor, in response to determining that a resource for transmitting the channel state information report, the medium access control control element, or the combination thereof is available prior to the second time, triggers a scheduling request to request a new resource for transmitting the channel state information report, the medium access control control element, or the combination thereof in response to a sidelink logical channel restriction parameter.
20 . The apparatus of claim 11 , wherein the sidelink restriction parameter comprises a PC5 logical channel restriction parameter.
