US 11,445,489 B2 · Techniques for downlink control channel location indication in wireless communications

Abstract

Methods, systems, and devices for wireless communications are described that provide for a location indicator transmission that may indicate a location of control channel resources that are to be monitored by a user equipment (UE) for control channel transmissions. A UE may receive the location indicator, and monitor the indicated control channel resources to receive downlink control information with an allocation of shared channel resources for the UE. The location indicator may include one or more parameters that allow a UE to receive the control channel transmissions according to a single decoding hypothesis. The location indicator may include one or more of a valid period of the location of the control channel transmissions, an interval at which control channel transmissions may be transmitted, an aggregation level used for the control channel transmissions, an index that identifies a first control channel element of the control channel transmissions, or combinations thereof.

Dependent claims

A method for wireless communication, comprising:

receiving, at a user equipment (UE), a location indicator transmission based at least in part on monitoring a set of resources specific to the location indicator transmission, the location indicator transmission having a location indicator that identifies downlink control channel resources that are to be monitored by the UE for downlink control information transmissions, wherein the receiving the location indicator transmission comprises identifying a search space of downlink transmission resources that are configured for transmission of the location indicator transmission, searching the search space for the location indicator transmission, and decoding the location indicator transmission responsive to the searching;
monitoring the downlink control channel resources based at least in part on the received location indicator;
receiving downlink control information on the downlink control channel resources based at least in part on the monitoring;
identifying, based at least in part on the downlink control information, downlink shared channel resources that have been allocated for shared channel transmissions to the UE;
and
receiving the shared channel transmissions via the downlink shared channel resources.

A user equipment (UE), comprising:

means for receiving, at the UE, a location indicator transmission based at least in part on monitoring a set of resources specific to the location indicator transmission, the location indicator transmission having a location indicator that identifies downlink control channel resources that are to be monitored by the UE for downlink control information transmissions, wherein the means for receiving the location indicator transmission comprise means for identifying a search space of downlink transmission resources that are configured for transmission of the location indicator transmission, means for searching the search space for the location indicator transmission, and means for decoding the location indicator transmission responsive to the searching;
means for monitoring the downlink control channel resources based at least in part on the received location indicator;
means for receiving downlink control information on the downlink control channel resources based at least in part on the monitoring;
means for identifying, based at least in part on the downlink control information, downlink shared channel resources that have been allocated for shared channel transmissions to the UE;
and
means for receiving the shared channel transmissions via the downlink shared channel resources.
