Systems and methods for managing resources for SL communications
Systems and methods for wireless communications are disclosed herein. In some arrangements, a wireless communication device determines whether a resource of a first resource set excluded from a second resource set is associated with a valid priority, and in response to determining that the resource excluded from the second resource set is associated with the valid priority, the wireless communication device reports reevaluation of the resource to one or more higher layers.
1 . A wireless communication method, comprising:
determining, by a wireless communication device, whether a resource of a first resource set excluded from a second resource set is associated with a valid priority; and
in response to determining that the resource excluded from the second resource set is associated with the valid priority, reporting reevaluation of the resource to one or more higher layers.
2 . The wireless communication method of claim 1 , wherein determining whether the resource excluded from the second resource set is associated with the valid priority comprises determining whether the resource is excluded from the second resource set by a hypothetical Sidelink (SL) Control Information (SCI).
3 . The wireless communication method of claim 2 , comprising determining that the resource excluded from the second resource set is not associated with the valid priority, which comprises determining that the resource is excluded by the hypothetical SL SCI.
4 . A wireless communication method, comprising:
determining, by a wireless communication device, that a resource of a third resource set is excluded from a second resource set based on a Reference Signal Receive Power (RSRP) measurement and that a priority threshold prio pre is configured;
in response to determining that the resource is excluded based on the RSRP measurement and that the priority threshold prio pre is configured, reporting preemption of the resource to one or more higher layers; and
in response to determining that the priority threshold prio pre is not configured and determining that the resource is not a member of the second resource set due to the RSRP measurement performed for the SCI with valid priority, reporting, by the wireless communication device, the preemption of the resource.
5 . The wireless communication method of claim 4 , wherein
in response to determining that the priority threshold prio pre is configured, the preemption of the resource is reported in response to determining that (1) the resource is not a member of the second resource set due to the RSRP measurement, (2) an associated reception priority prio RX is less than the priority threshold prio pre , and (3) a transmission priority prio TX is greater than the reception priority prio RX .
6 . The wireless communication method of claim 2 , comprising:
determining, by a wireless communication device, that the hypothetical SLSCI has a periodicity value, the periodicity value being a value from a value set.
7 . The wireless communication method of claim 6 , wherein
the wireless communication device has not monitored a slot;
the hypothetical SL SCI is received hypothetically in the slot; and
a resource reservation field in the hypothetical SL SCI is set to the periodicity value.
8 . The wireless communication method of claim 6 , wherein
the value set is one of:
a configured set received from higher layer; or
a subset of the configured set from the higher layer, the subset comprising values greater than, or greater than or equal to, a low boundary of the value set.
9 . The wireless communication method of claim 8 , wherein
the low boundary is a value configured or preconfigured by a higher layer, a network, or a base station; or
the low boundary is one of multiple values configured or preconfigured by the higher layer, the network, or the base station, each of the multiple values mapping to a priority, wherein the one of the multiple values corresponds to a SL priority of a priority of packets the wireless communication device is to transmit or a priority of the first resource set.
10 . A wireless communication device, comprising:
at least one processor configured to:
determine whether a resource of a first resource set excluded from a second resource set is associated with a valid priority; and
in response to determining that the resource excluded from the second resource set is associated with the valid priority, report reevaluation of the resource to one or more higher layers.
11 . The wireless communication device of claim 10 , wherein to determine whether the resource excluded from the second resource set is associated with the valid priority comprises to determine whether the resource is excluded from the second resource set by a hypothetical Sidelink (SL) Control Information (SCI).
12 . The wireless communication device of claim 11 , wherein the at least one processor are configured to determine that the resource excluded from the second resource set is not associated with the valid priority, which comprises determining that the resource is excluded by the hypothetical SL SCI.
13 . The wireless communication device of claim 11 , wherein the at least one processor are configured to:
determine that the hypothetical SL SCI has a periodicity value, the periodicity value being a value from a value set.
14 . The wireless communication device of claim 13 , wherein
the wireless communication device has not monitored a slot;
the hypothetical SL SCI is received hypothetically in the slot; and
a resource reservation field in the hypothetical SL SCI is set to the periodicity value.
15 . The wireless communication device of claim 13 , wherein the value set is one of:
a configured set received from higher layer; or
a subset of the configured set from the higher layer, the subset comprising values greater than, or greater than or equal to, a low boundary of the value set.
16 . The wireless communication device of claim 15 , wherein
the low boundary is a value configured or preconfigured by a higher layer, a network, or a base station; or
the low boundary is one of multiple values configured or preconfigured by the higher layer, the network, or the base station, each of the multiple values mapping to a priority, wherein the one of the multiple values corresponds to a SL priority of a priority of packets the wireless communication device is to transmit or a priority of the first resource set.
17 . A wireless communication device, comprising:
at least one processor configured to:
determine that a resource of a third resource set is excluded from a second resource set based on a Reference Signal Receive Power (RSRP) measurement and that a priority threshold prio pre is configured;
in response to determining that the resource is excluded based on the RSRP measurement and that the priority threshold prio pre is configured, report preemption of the resource to one or more higher layers; and
in response to determining that the priority threshold prio pre is not configured and that the resource is not a member of the second resource set due to the RSRP measurement performed for the SCI with valid priority, report the preemption of the resource.
18 . The wireless communication device of claim 17 , wherein the at least one processor are configured to:
in response to determining that the priority threshold prio pre is configured, report the preemption of the resource in response to determining that (1) the resource is not a member of the second resource set due to the RSRP measurement, (2) an associated reception priority prio RX is less than the priority threshold prio pre , and (3) a transmission priority prio TX is greater than the reception priority prio RX .
