Abstract: Improved solutions for reliable physical channel, e.g. Physical Downlink Shared Channel (PDSCH) reception during wireless communications, for example during 3GPP New Radio (NR) communications include continuous channel repetitions that cross slot boundaries, channel repetitions with multiple frequency hops, and joint-repetition channel estimation that uses demodulation reference signals from at least two channel repetitions for the channel estimation. In one aspect, reliable PDSCH reception may have the benefit of aiding target UEs and serving base stations in implementing reliable Multicast and Broadcast Services (MBS).

Abstract: Systems and methods disclosed herein use channel state information (CSI) reports from a user equipment (UE) having additional CSI beyond CSI directly derived according to a current MIMO configuration between a base station and the UE. In some embodiments, a channel quality indicator (CQI) according to a selected layer of a plurality of layers used to receive the MIMO transmission as determined relative to the MIMO transmission is reported. In some embodiments, a precoding matrix indicator (PMI) according to a selected layer of a plurality of layers useable to receive rank 1 transmissions is reported along with a CQI determined according to that layer, or according to a layer used to receive the MIMO transmission as determined relative to the MIMO transmission. In some embodiments, a base station configures a UE to report more fulsome CSI according to each of a plurality of ranks.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing one or more low-power wake-up receivers (LP-WUR) at the UE and for implementing mechanisms for improving receiver sensitivity loss for the LP-WUR. According to some aspects, apparatuses and methods are provided to improve the receiver sensitivity loss for the LP-WUR using time domain coverage improvement, power domain coverage improvement, spatial domain coverage improvement, and/or frequency domain coverage improvement.

Abstract: A UE may coordinate the use of a low Power Wake-Up Radio (LR) and a main radio (MR) to determine a Radio Resource Management (RRM) measurement. The UE may enter a deep sleep state by turning off a MR and turning on a LR. The UE may measure the serving cell quality when in the deep sleep state, and enter a normal state by turning on the MR, when the serving cell quality is less than a threshold. The UE may perform a neighbor cell measurement, when in the normal state when a serving cell measurement meets a criteria.

Abstract: This disclosure relates to techniques for configuring listen before talk and short control signaling in unlicensed spectrum in a wireless communication system. A wireless device may establish a wireless link with a cellular base station on a cell in unlicensed spectrum. The wireless device may receive listen-before-talk configuration information, where the listen-before-talk configuration information indicates whether listen-before-talk is configured for the wireless link. The wireless device may receive short control signaling configuration information, where the short control signaling configuration information indicates whether short control signaling is enabled for one or more types of control signaling. The wireless device may perform short control signaling with the cellular base station on the wireless link when short control signaling is enabled. The short control signaling performed between the cellular base station and the wireless device may include either or both of uplink transmissions or downlink transmissions.

Abstract: This disclosure relates to apparatuses and methods for providing and managing reception feedback for multicast and broadcast services (MBS). A base station (BS) may select and communicate, to a group of user equipment devices (UEs), configuration parameters for MBS communications, such as an indication of an MBS retransmission procedure for an MBS service. The BS may also transmit, to the group of UEs, an MBS data communication. A first UE may receive the MBS data communication, but may determine that the received MBS data communication is corrupted. The first UE may respond by transmitting, to the BS, a negative-acknowledgement (NACK) message. The BS may retransmit the MBS data communication either as an MBS transmission or as a unicast transmission, based on the configuration parameters. The first UE may monitor the appropriate resources to receive the retransmitted MBS data communication, based on the configuration parameters.

Abstract: A method for wireless communication includes: requesting transmission, by a wireless device, of uplink (UL) transmissions to a wireless station; receiving, by the wireless device, a UL cancellation indication (CI) to be applied to a determined reference region; determining, by the wireless device, a set of UL resources for cancellation based on the UL CI received from the wireless station (e.g., by determining an indication of particular interlaces and/or particular Physical Resource Blocks within such interlaces that are to be canceled), wherein at least a subset of the UL resources for cancellation are interlaced; and canceling, by the wireless device, UL transmissions over at least the determined set of UL resources for cancellation (i.e., additional UL transmissions may be cancelled, too). The wireless device may then perform UL transmissions that do not overlap with the determined set of UL resources for cancellation in any UL CI to the wireless station.

Abstract: Switching schemes at a mobile device may include, in response to being within range of a transmission and reception point (TRP) of a plurality of TRPs associated with a high speed train (HST), decoding a communication received from a network. The communication may include a first radio resource control (RRC) information element (IE) having an HST configuration associated with an HST scheme. The HST configuration may be applied to thereby operate using the HST scheme. In response to being out of range of the plurality of TRPs associated with the HST, a communication received from the network may be decoded. The communication may include a second RRC IE having a non-HST configuration associated with a non-HST scheme. The non-HST configuration may be applied to thereby operate using the non-HST scheme.

Abstract: A base station of a network provides a user equipment (UE) with information relating to monitoring a Physical Downlink Control Channel (PDCCH) of multiple component carrier (CCs) in a carrier aggregation (CA) scheme. The base station configures a first CC and a second CC of a CA combination for a user equipment (UE) and provides the UE with information for the CA combination, wherein the information comprises an indication whether the first CC and the second CC are collocated.
