摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may receive, from a base station, an indication of a configuration for a multi-panel transmission power control (TPC) command to be transmitted by the base station. The UE may also receive, according to the indicated configuration, a downlink control information (DCI) message including a set of TPC commands. The UE may determine, based on the set of TPC commands, a first transmit power for a first antenna panel of the UE and a second transmit power for a second antenna panel of the UE. The UE may transmit an uplink signal using the first antenna panel at the first transmit power and the second antenna panel at the second transmit power.

摘要： Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may support simultaneous transmissions of data on an uplink shared channel that is associated with a first cell, and control information such as uplink control information on an uplink control channel associated with a second cell. The UE may receive scheduling information that indicates a time domain overlap of scheduled transmissions associated with the uplink control channel and the uplink shared channel, and a multiplexing configuration for the UE which indicates whether the UE is to multiplex the uplink control information on the uplink control channel or whether the UE is to multiplex the uplink control information on the uplink shared channel.

摘要： Determining, by a user equipment (UE) of a wireless communication system, that a physical uplink control channel (PUCCH) transmission of the UE carrying uplink control information (UCI) will collide upon transmission with another physical uplink shared channel (PUSCH) transmission of the UE. The UE then multiplexes, in response to the determining, the UCI on the PUSCH transmission based on one or more of the beam of the PUCCH transmission and the beam of the particular PUSCH transmission.

摘要： A base station may perform a beamforming for a UE group including UEs that are disposed spatially close to each other for MU-MIMO. The base station may generate group common DCI including a beam indication and/or a PL-RS indication for the UE group. The ID included in the group common DCI may be group specific for the UE group or UE specific for a specific UE. The beam indication for different channels may be indicated by an RNTI or an RRC.

摘要： A user equipment (UE) may initiate a random access (RACH) procedure using an uplink resource selected based on a corresponding received synchronization signal block. The UE may detect a random access procedure trigger. The UE may configure a selection threshold time. The selection threshold time may be based at least in part on a latency requirement of the UE. The UE may select a synchronization signal block having a corresponding uplink resource within the selection threshold time. The synchronization signal block and corresponding uplink resource satisfy one or more parameters or conditions. The UE may transmit a random access preamble on the corresponding uplink resource.

摘要： Certain aspects of the present disclosure relate to techniques for determining resource elements REs used for Coordinated Multipoint (CoMP) transmission schemes. The techniques generally include determining, by a User Equipment (UE), a set of data REs used for Coordinated Multipoint (CoMP) operation. The determination is based on a CoMP scheme and data REs available to particular base stations involved in the CoMP operation. The technique further includes processing data received via the CoMP operation on the determined set of data REs.

摘要： Downlink rate adaptation in wireless communication systems are disclosed in which a UE reports RIs for both interference-free and interference-limited subframes. In general, the RI for the interference-free subframes will be higher than the RI reported for the interference-limited subframes. However, an eNB selects an RI and a transmission rate for interference-limited subframes based on what the UE can sustain instead of based only on the RI reported by the UE.

摘要： Certain aspects of the present disclosure provide techniques and apparatuses for wireless communications. According to certain aspects, a set of protected resources, allocated to a base station of a first cell, that are protected by restricting transmissions of a second cell is determined and received power of a first reference signal from the base station in the set of resources is measured. According to certain aspects, a subset of one or more neighbor base stations that have reduced interference in a set of protected resources is determined and received power measurements for the subset of neighbor cells is excluded when calculating receive signal quality measurements for the subframe.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided for separating control transmissions and data transmissions within the coverage area of a plurality of transmission/reception points or points that are geographically displaced, the plurality of points comprising a macro node and a plurality of remote radio heads (RRHs) coupled to the macro node. Separating control transmissions and data transmissions in the macro node/RRH configuration may allow UEs to be associated with one set of transmission points for data transmissions and the same set or a different set of transmission points for common control signaling. Separating control transmissions and data transmissions may also allow for faster reconfiguration of antenna ports used for UE data transmission compared with reconfiguration via a handover process.
