摘要： Apparatuses, methods, and systems are disclosed for downlink assignments for downlink control channels. One method includes, in response to an assignment group comprising a first assignment: determining a first data channel allocation comprising resources allocated to a first data channel; determining a first DMRS symbol location associated with the first data channel based on the first assignment, a first set of OFDM symbols, and a second set of OFDM symbols; and decoding the first data channel. The method includes, in response to the assignment group comprising a second assignment: determining a second data channel allocation comprising resources allocated to a second data channel; determining a second DMRS symbol location associated with the second data channel based on the second assignment, the first set of OFDM symbols, and the second set of OFDM; and decoding the second data channel.

摘要： Apparatuses, methods, and systems are disclosed for power headroom reporting for multiple uplink carriers. One apparatus includes a transceiver that receives a configuration of a plurality of UL carriers for a serving cell. The first apparatus includes a processor that determines that a PHR has been triggered, where the PHR for the serving cell is determined to be a virtual PHR. The processor determines a default power control parameter set for the serving cell and calculates a PHR for the serving cell. Here, calculating the PHR includes calculating a virtual PH based on the default power control parameter set. The processor transmits (via the transceiver) the calculated PHR for the serving cell.

摘要： Apparatuses, methods, and systems are disclosed for directional transmission/reception of groupcast and unicast communication. One apparatus (800) includes a transceiver (825) that performs (1005) a plurality of sidelink transmissions (115, 501) with different spatial directions and receives (1015) a feedback transmission from a receiving UE. Here, each of the plurality of sidelink transmissions (115, 501) is carried out from one of a plurality of antenna panels (407), where the sidelink transmissions contain an embedded sidelink reference signal. The apparatus (800) includes a processor (805) that determines (1020) a best antenna panel (407) for sidelink transmission based on the received feedback transmission. An apparatus is also disclosed that identifies a set of candidate sidelink resources and measures signal strength using a plurality of beams at a plurality of antenna panels. It excludes at least one sidelink resource from the set of candidate sidelink resources, where the exclusion is on a per-antenna-panel basis. The apparatus selects a sidelink resource from the remaining candidate sidelink resources for performing sidelink communication using a beam at an antenna panel. Yet another apparatus dentifies a downlink pathloss between the apparatus and a RAN node and identifies at least one first antenna panel facing the RAN node and simultaneously used for sidelink communication. Here, the apparatus includes a plurality of antenna panels used for sidelink communication. The apparatus reduces a sidelink power for the at least one first antenna panel based on the downlink pathloss, while ignoring the downlink pathloss for sidelink power control for the remaining antenna panels used for sidelink communication.

摘要： Apparatuses, methods, and systems are disclosed for uplink power control. One method includes: receiving a message that configures a set of resources that each includes a downlink resource or an uplink sounding resource and is associated with an uplink transmission beam pattern; receiving scheduling information for an uplink transmission that is associated with a resource of the set of resources; determining an uplink transmission beam pattern associated with the resource; determining a configured maximum output power for the uplink transmission beam pattern that is based on an antenna array property associated with the uplink transmission beam pattern; determining a transmit power for the uplink transmission based on the configured maximum output power; and performing the uplink transmission using the uplink transmission beam pattern based on the transmit power.

摘要： PDSCH resource allocations can be received. Different PDSCH resource allocations of the PDSCH resource allocations can be associated with different spatial filters for a user equipment. A pre-emption indication that indicates pre-empted resources can be received. A determination can be made as to whether the pre-emption indication is applicable to a first or second PDSCH resource allocation, both the first and the second PDSCH resource allocations, or no PDSCH resource allocation. A first PDSCH corresponding to the first PDSCH resource allocation can be decoded based on no transmission being present for a UE in the pre-empted resources in response to determining the pre-emption indication is applicable to the first PDSCH resource allocation. The pre-emption indication can be a first pre-emption indication with a first bit-field size and can be indicated in a DCI containing a second pre-emption indication with a second bit-field size different than the first bit-field size.

摘要： At least two PDSCH resource allocations can be received. Different PDSCH resource allocations of the at least two PDSCH resource allocations can be associated with different spatial filters for a UE.

A determination can be made as to whether the pre-emption indication is applicable to a first PDSCH resource allocation, a second PDSCH resource allocation, both PDSCH resource allocations, or no PDSCH resource allocation of the at least two PDSCH resource allocations. A first PDSCH corresponding to the first PDSCH resource allocation can be decoded based on no transmission being present for the UE in the pre-empted resources in response to determining the pre-emption indication is applicable to the first PDSCH resource allocation and not applicable to the second PDSCH resource allocation.

摘要： Apparatuses, methods, and systems are disclosed for downlink assignments for downlink control channels. One method includes determining a third set of downlink control channel monitoring occasions that comprises first downlink control channel monitoring occasions and second downlink control channel monitoring occasions, and associated search spaces correspond to two different control resource sets comprising a first control resource set and a second control resource set, wherein: demodulation reference signal ports of the first control resource set are quasi-collocated with a first set of reference signals; demodulation reference signal ports of the second control resource set are quasi-collocated with a second set of reference signals. The method includes monitoring one or more downlink control channel candidates in at least one slot of the third set of monitoring occasions if the one or more downlink control channel candidates carry the same downlink control information.

摘要： A method and apparatus provide for detecting that an event triggering a power headroom report for a first activated serving cell has occurred. A first physical uplink shared channel resource corresponding to a first physical uplink shared channel transmission is identified that comprises an initial transmission of a transport block since the power headroom report was triggered. A determination is made as to whether the first physical uplink shared channel resource corresponds to a configured grant or is in response to uplink grant downlink control information received on a physical downlink control channel since the power headroom report was triggered. Whether the power headroom report is based on an actual transmission or a reference format is determined for each component carrier corresponding to respective downlink control information the user equipment receives until an expiration of a time window measured from the event. The power headroom report is then transmitted on the first physical uplink shared channel transmission.

摘要： A configuration of a first search space for monitoring control channel candidates over a first set of symbols can be received. A configuration of an alternative set of search spaces containing at least a second search space for monitoring control channel candidates over a second set of symbols can be received. A DCI scheduling an uplink transmission over a third set of symbols can be received. A determination can be made as to whether the uplink transmission overlaps with the first set of symbols. Control channel candidates in the first search space can be monitored when the uplink transmission does not overlap with the first set of symbols. Control channel candidates can be monitored in the second search space instead of the first search space when the uplink transmission overlaps with the first set of symbols.
