Abstract:
A method of wireless communication, by a user equipment (UE), includes receiving, from a first transmission and reception point (TRP) operating in a first band, assistance information comprising collocation information for both a second TRP operating in a second band and a communication node operating in the first band. The method also includes receiving, from the first TRP, configuration information for one or more reference signals (RSs) associated with the communication node. The method further includes communicating with the second TRP based on one or more features of the second band estimated from the one or more RSs.
Abstract:
A scheduling entity can schedule regular or periodic control resources (CORESETs) that are relatively sparse in the time domain compared to dynamic CORESETS. Sparsely scheduled regular CORESETs can reduce the overhead incurred by a user equipment for monitoring the control channels in the CORESETs or search spaces. When the network has a burst of data to send, the scheduling entity can use downlink control information (DCI) piggybacked in physical downlink shared channel (PDSCH) resources to schedule dynamic CORESETs between the regular CORESETs. The dynamic CORESETs can provide resources for a PDSCH and/or physical downlink shared channel (PUSCH).
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a multi-slot grant for one of uplink communication or downlink communication. The UE may communicate in the multi-slot grant based at least in part on information that provides an indication of one or more time gaps for the multi-slot grant. Numerous other aspects are provided.
Abstract:
Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). In some cases, if certain conditions are met, a user equipment (UE) may follow QCL assumptions for a physical downlink shared channel (PDSCH) scheduled by a same PDCCH that indicated the dynamic CORESET. An example method by a UE generally includes receiving at least one downlink control information (DCI), of a first physical downlink control channel (PDCCH), that schedules at least one dynamic CORESET; and receiving a second PDCCH in the dynamic CORESET, wherein the UE is to apply at least one QCL assumption associated with a PDSCH for the at least one dynamic CORESET if one or more conditions are met.
Abstract:
A non-terrestrial network is provided that includes a satellite that transmits an orbital parameter message to a user equipment. The user equipment processes the orbital parameter message to determine a current range from the user equipment to the satellite based upon the received orbital parameter message, a timing offset and a frequency offset for an uplink transmission to the satellite.
Abstract:
A communication satellite system provides for spectral efficient data transmissions by a gateway to multiple user terminals by way of a satellite. The gateway transmits multiple blocks in a single slot, each block intended for one of the user terminals, where each block is encoded and modulated according to a scheme that may be different for each intended user terminal. Upon re-transmission of a block if that block is lost or received in error, the block may be encoded and modulated according to another scheme that is less spectrally efficient than in the first transmission of the block.
Abstract:
Method and apparatus for time or frequency synchronization of radio signals transmitted by user terminals in communication with a gateway through a satellite is provided. The satellite may be part of a non-synchronous satellite communication system, such as a low-earth orbit (LEO) satellite communication system for data, voice or video communications. Times of transmission of return link radio signals from the user terminals may be adjusted such that the signals arrive at the satellite or at the gateway without large time delay differentials. Carrier frequencies of return link radio signals transmitted from the user terminals may be adjusted such that the signals arrive at the satellite or at the gateway without large frequency offset differentials.
