US 11,963,181 B2 · Base-station-initiated grant revoke

Abstract

This document describes techniques and systems that enable a base-station-initiated grant revoke. The techniques and systems allow a base station to generate and send a grant-revocation message (GRM) to a user equipment (UE) to revoke a scheduled uplink (UL) or downlink (DL) grant from the base station. The base station can transmit the GRM to the UE using a variety of techniques. For example, based on a trigger event, the base station may assign a UE identifier, such as a specific radio network temporary identifier (RNTI), to the UE and transmit the GRM to the UE using a revoke-physical-downlink-control-channel (R PDCCH) transmission that is associated with the UE identifier. These techniques allow the base station to revoke a scheduled UL or DL grant, which can enable the UE to quickly address timing-critical resource allocation issues and mitigate the effects of adverse operating conditions.

Claims20

Dependent claims

A method performed by a base station for reallocating a scheduled grant for a first user equipment (UE) in a wireless network to a second UE in the wireless network, the method comprising:

detecting a trigger event;
in response to detecting the trigger event, determining to revoke at least a portion of the scheduled grant;
generating a grant-revocation message (GRM) that indicates to terminate a scheduled transmission that uses at least the portion of the scheduled grant;
revoking at least the portion of the scheduled grant by transmitting the GRM to the first UE;
and
reallocating at least the portion of the scheduled grant to the second UE.

3 more elements

A base station, comprising:

a radio-frequency (RF) transceiver;
at least one processor;
and
a computer-readable storage memory system including processor-executable instructions that, responsive to execution by at least the one processor, cause the base station to perform operations comprising:
detecting a trigger event;
in response to detecting the trigger event, determining to revoke at least a portion of a scheduled grant for a first user equipment (UE) in a wireless network;
generating a grant-revocation message (GRM) that indicates to terminate a scheduled transmission that uses at least the portion of the scheduled grant;
revoking at least the portion of the scheduled grant by transmitting the GRM to the first UE;
and
reallocating at least the portion of the scheduled grant to a second UE in the wireless network.
