Abstract: Techniques described herein permit a narrowband Internet of Things (NB-IoT) user equipment (UE) to combine narrowband reference signals (NRS) with other signals, which the NB-IoT UE already receives, to improve measurement accuracy. The UE may report whether the UE is capable of combining the NRS with another signal to determine a combined signal quality parameter, and may report the combined signal quality parameter to a base station.

Abstract: A device, such as a base station or user equipment (UE), may identify a narrowband reference signal (NB-RS) energy per resource element (EPRE) for a NB-RS to be transmitted in a wireless transmission. The device may identify a ratio of a narrowband physical downlink shared channel (N-PDSCH) EPRE to the NB-RS EPRE for orthogonal frequency division multiplexing (OFDM) symbols containing neither a cell-specific reference signal (CRS) nor a NB-RS. In deployments where NB transmissions are transmitted in a guard-band adjacent to a wideband system bandwidth, a device may identify a second ratio for N-PDSCH EPRE to CRS EPRE within OFDM symbols containing CRS. In deployments where NB transmissions are transmitted in-band with the wideband system bandwidth, a device may identify a third ratio of NB-RS EPRE to CRS EPRE, and a fourth ratio of N-PDSCH EPRE to NB-RS EPRE within OFDM symbols containing NB-RS transmissions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a transmission power for an uplink shared channel communication based at least in part on at least one of a code rate parameter, a block length parameter, or a target block error rate parameter associated with the uplink shared channel communication. In some aspects, the user equipment may transmit the uplink shared channel communication using the transmission power based at least in part on determining the transmission power. Numerous other aspects are provided.

Abstract: Aspects relate to supporting power control for physical uplink control channel (PUCCH) transmissions on an uplink secondary component carrier (SCC) of a wireless communication system. In some aspects, a user equipment (UE) receives a power control configuration from a base station for use by the UE for a PUCCH transmission on a selected uplink SCC. The UE then transmits, based at least in part on the power control configuration, the PUCCH to the base station on the selected uplink SCC. Closed-loop and open-loop power control examples are provided. In some aspects, common or shared power control configurations are provided by the base station for use with each component carrier of a PUCCH group. In other aspects, carrier-specific power control configurations are provided by the base station.

Abstract: A wireless communication device can flexibly change subcarrier spacing (SCS) and/or cyclic prefix (CP) in wireless communication. The wireless communication device can transmit, in a first sidelink resource of a sidelink resource pool, a first sidelink transmission using a first configuration of subcarrier spacing (SCS) and cyclic prefix (CP). The wireless communication device can further transmit, in a second sidelink resource of the sidelink resource pool, a second sidelink transmission using a second configuration of SCS and CP, the second configuration being different from the first configuration in terms of at least one of an SCS or a CP. The techniques allow more efficient switching between SCS and CP configurations within a resource pool in the same bandwidth part.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for providing feedback. For example, a user equipment (UE) may receive, from a network node, a configuration of a search space comprising time and frequency resources available to the network node for communicating a downlink control channel, the configuration indicating a feedback process type corresponding to the search space. The UE may also receive, from the network node, the downlink control channel in the search space. The UE may also receive a downlink transmission scheduled by the downlink control channel. The UE may selectively provide feedback to the network node regarding decoding of the downlink transmission according to the feedback process type corresponding to the search space.

The method also includes determining, by the UE, a plurality of potential satellites for selecting a first cell to camp on, the first cell associated with a first satellite. The method includes performing cell reselection, by the UE, to select a cell associated with a second satellite using a selection condition. The method further includes establishing, by the UE, a connection with the second satellite for paging monitoring or wireless communications. Other aspects and features are also claimed and described.
