A control device includes a logic slot allocation unit and a logic slot notification unit. The logic slot allocation unit generates a set of one or more terminals such that each terminal included in the same set has at least one receiving base station, which is a base station that receives wireless communication from the terminal, and allocates each generated set to a logic slot that has a different combination of a channel and a transmission sequence number. The logic slot notification unit notifies each terminal of the logic slot that was allocated to the terminal.

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.

The method includes performing at least one first monitoring of a power savings channel of a physical downlink control channel (PDCCH) for control information, the PDCCH being associated with at least one base station, the control information including a power saving downlink control information (PS-DCI) format, the control information providing an indication to start a timer for an ON duration of a discontinuous reception (DRX) cycle for a user equipment (UE) to monitor the PDCCH. The method further includes performing a random-access channel (RACH) procedure with the at least one base station based on the control information. The network node performs the method.

Aspects relate to signaling relating to a non-linearity model for power amplifier circuitry of a transmitting device. The power amplifier circuitry may apply digital pre-distortion (DPD) to a signal prior to amplification and transmission of the signal. A receiving device may apply digital post-distortion (DPoD) to a signal received from the transmitting device where the DPoD is based on the non-linearity model. The transmitting device may send to the receiving device non-linearity parameters for the non-linearity model.

User equipment (UE)-initiated accesses within a cellular network are optimized to account for cell size and to reduce signaling overhead. A fixed set of preamble parameter configurations for use across a complete range of cell sizes within the cellular network is established and stored within each UE. A UE located in a given cell receives a configuration number transmitted from a nodeB serving the cell, the configuration number being indicative of a size of the cell. The UE selects a preamble parameter configuration from the fixed set of preamble parameter configurations in response to the received configuration number and then transmits a preamble from the UE to the nodeB using the preamble parameter configuration indicated by the configuration number.

Various embodiments of the present disclosure provide a method for random access. The method which may be performed by a network node comprises determining configuration information for a contention free preamble in a random access occasion, based at least in part on mapping between synchronization signal and physical broadcast channel blocks and preambles for two-step random access in the random access occasion. The contention free preamble is applicable for the two-step random access. The method further comprises transmitting the configuration information to a terminal device. According to some embodiments of the present disclosure, an association between signaling transmissions in a two-step random access procedure can be configured flexibly and efficiently.
