    摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a response message associated with a random access message, wherein the response message includes an identifier of the UE; select a format of an uplink channel or an uplink signal for acknowledging successful decoding of the response message; determine a transmit power for hybrid automatic repeat request (HARQ) acknowledgment (ACK) information based at least in part on at least one of: a message type of the response message, a mode of random access associated with the random access message, a power control configuration used by a previous transmission of the random access message, or the format of the uplink channel or the uplink signal; and transmit the HARQ ACK information using a power control procedure based at least in part on the transmit power. Numerous other aspects are provided.

    摘要： Signaling design for interlaced frequency divisional multiplex (IFDM) demodulation reference signals (DMRS) is discussed in which a dynamic indication is provided to a user equipment (UE) from a serving base station that allows the UE to configure transmission of DMRS according to either a single carrier frequency divisional multiplex (SC-FDM) or IFDM configurations, as indicated by the dynamic indication. The IFDM configuration may be applicable to either regular uplink subframes or within the uplink portion of special subframes. In some aspects, power boosting may be provided for the DMRS in order to equalize transmit power between decimated DMRS transmitted with the data tones. Additional aspects may also provide for different offsets to be used depending on the type of uplink control signal transmitted.

    摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of channel state processes scheduled to be performed. The UE may receive a channel state feedback request corresponding to another set of channel state processes. The combination of the set of channel state processes and the other set of channel state processes may be greater than an amount that the UE may process at a given time. The UE may determine a priority for the channel state processes either on an individual or group basis. The UE may determine channel state process (es) to drop based on the determined priorities, and may perform the remaining channel state processes. The UE may generate and transmit a channel state feedback report message based on the performed channel state processes.

    摘要： Methods, systems, and devices for wireless communications are described. One or more multiple access-capable user equipments (UEs) may be grouped together for transmitting uplink multiple access communications to a base station, where the UEs may be assigned to the group based on similar capabilities or service requirements. The UE may receive configuration information based at least in part on the group to which the UE has been assigned. When assigned to a group, the UEs may also receive a group-specific scrambling code for the uplink multiple access communications, a group-specific power control for the uplink multiple access communications, time and frequency resources to be used for the uplink multiple access communications specific to the group, or a combination thereof. Additionally, the specific time and frequency resources may be defined by multiple access resource units.
