摘要： A base station (BS) may receive a plurality of repetitions of a Physical Uplink Control Channel (PUCCH) from a user equipment (UE), and accumulate the received repetitions to obtain a resultant signal. The ability to accumulate repetitions enables the base station to experience a higher probability of successful recovery of the PUCCH payload bits than if decoding were based on the reception of a non-repeated transmission of the PUCCH. The base station may configure the number of repetitions, the temporal gap between the repetitions, and mode of repetition of the PUCCH. In an intra-slot mode, more than one copy may be received from each configured slot, with or without frequency hopping. In an inter-slot mode, one copy is received per configured slot. Different repetitions may be transmitted by the UE in different directions, according to a spatial consistency pattern.

摘要： Technology is provided for supporting different numerologies for concurrent intra-frequency measurements and downlink data reception. A user equipment (UE) may send a message to the a wireless network to indicate whether the UE supports a mixed numerology wherein a different subcarrier spacing (SCS) is used in a serving cell or a neighboring cell for concurrent processing of at least two of: intra-frequency measurement by the UE of a synchronization signal block (SSB); intra-frequency measurement by the UE of a channel state information reference signal (CSI-RS) for mobility; and reception by the UE of a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH). Based on the indication, the network may configure at least one of a CSI-RS measurement expectation, an SSB measurement expectation, and a scheduling restriction for reception of the PDCCH or the PDSCH by the UE.

摘要： A user equipment (UE) configured to transmit a scheduling request (SR) to a second UE which causes the second UE to determine a set of sidelink transmission resources for use by the UE. The UE may then receive information regarding a determined set of sidelink transmission resources from the second UE and then transmit sidelink communications using at least a subset of the determined set of sidelink transmission resources. The determined set of sidelink transmission resources may be recommended and reserved or non-reserved resources. The UE may transmit configuration information concerning transmission resources to the second UE to be used in transmitting, the SR. The second UE may monitor the channel for arrival of the resources. The SR may be encoded as a cyclic shift of the SR corresponding to an ACK-only sequence, an ACK/NACK sequence, or a certain sequence of the SR based on a configuration index.

摘要： This disclosure relates to techniques for performing wireless communications by a network in communication with a UE that is moving rapidly. The network may adapt communication techniques in response to the CEs motion. For example, reference signals may be transmitted to the UE from additional transmission and reception points and/or using different configurations.

摘要： A method for Resource Allocation for Msg-3 Transmission on an unlicensed spectrum may include receiving a random access response (RAR) grant comprising a 12-bit frequency domain resource allocation (FDRA) field. If the resource allocation type is type-1 some embodiments may zero padding the FDRA field to interpreting the 12-bit FDRA and determine a starting position of allocated resources where a Scheduled PUSCH Transmission is transmitted in an unlicensed spectrum. Some embodiments may use a virtual Bandwidth Part (BWP) to obtain a starting position and a length of allocated resources.

摘要： Embodiments are presented herein of apparatuses, systems, baseband processors, and methods for performing vehicle-to-everything sidelink communication. A wireless device receives first control information through a sidelink control channel specifying one or more first time slots for the wireless device to transmit a first acknowledgment message over a sidelink feedback channel. The wireless device transmits second control information through the sidelink control channel specifying one or more second time slots for the wireless device to receive a second acknowledgment message over the sidelink feedback channel. The first and second time slots at least partially overlap, and it is determined whether the first data packet or the second data packet has a higher priority. The acknowledgment message associated with the higher priority data packet is transmitted or received during at least a subset of the overlapping time slots.

摘要： The present application relates to devices and components including apparatus, systems, and methods to provide SCell activation. In one example, a UE may support carrier aggregation in a high speed mode, such FR1 CA in HST. Serving cells can be particularly configured for the carrier aggregation based on the UE's capability to support carrier aggregation in the high speed mode. Additionally or alternatively, an SCell activation procedure can be performed based on this capability.

摘要： 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).

摘要： Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.
