Specifically, provided is a method and an apparatus for supporting same, the method comprising the steps of obtaining random access procedure-related message A, message A including a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); transmitting message A; and receiving random access procedure-related message B as a response to message A, wherein the PUSCH comprises a demodulation reference signal (DM-RS), and PRACH preamble is mapped to (i) one or more DM-RS ports and (ii) one or more DM-RS sequences on the basis of indices of respective (i) one or more DM-RS ports and indices of respective (ii) one or more DM-RS sequences.

A communications device is provided. The communications device comprises transceiver circuitry configured to transmit signals and receive signals to and from a wireless communications network, and controller circuitry. The controller circuitry is configured in combination with the transceiver circuitry to transmit to the wireless communications network, whilst operating in an inactive state, one or more signals comprising uplink data using a first of a plurality of beams each for transmission in a different one of a plurality of spatial directions, to detect, whilst operating in the inactive state, that the first beam satisfies a beam failure condition a specified number of consecutive times, and subsequently to determine, whilst operating in the inactive state, that the first beam has failed.

Provided is an information processing method and apparatus, a device and a storage medium. The information processing method includes: radio capability information is sent to a next generation NodeB (gNB); where the radio capability information includes user equipment (UE) capability information.

Systems and methods in which one or more wireless communication stations implement duplex-mode remediation to facilitate the signal communication when an issue with respect to self-interference is identified are described. Duplex-mode remediation may be implemented for various communication scenarios, such as for random access phase communications, for communications having different priorities, etc. A wireless communication station may implement one or more changes with respect to the full duplex operation of the wireless communication station based upon determining that an issue with respect to self-interference may be, or is being, experienced, such as to provide for a wireless communication station operating in an in-band full duplex mode to increase interference cancellation and/or to fall back to a sub-band full duplex mode or a half duplex mode, to provide for a wireless communication station operating in a sub-band full duplex mode to increase interference cancellation and/or to fall back to a half duplex mode.

A method is disclosed herein for reducing energy consumption in a wireless device. A wireless device (e.g., a user equipment) can provide an indication to a network node (e.g., a base station) to indicate that the wireless device will prioritize energy consumption reduction over some network requirements (e.g., latency and/or scheduling flexibility requirements). Accordingly, the wireless device can perform certain power-saving actions to reduce energy consumption. The network node, upon receiving the indication from the wireless device, can perform certain network-related actions to assist the wireless device in reducing energy consumption. As a result, it is possible for the wireless device to reduce energy consumption and complexity, thus helping to prolong battery life in the wireless device.

The technology of this application relates to a random access method, applied to the communication field. The method includes a terminal device sends, to a network device, a first message used to establish a wireless connection, the terminal device receives, a connection response sent by the network device, where the connection response includes information about a first polarization parameter, and when accessing the network device based on the connection response, the terminal device determines, based on the information about the first polarization parameter included in the connection response, whether the terminal device is qualified to access the network device. A dimension, namely, a polarization parameter, is introduced into a random access procedure, so that a preamble capacity is increased, a problem that the network device cannot identify a colliding terminal device is alleviated, and efficiency of establishing a communication connection between the terminal device and the network device is improved.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating at least one of: a configuration for requesting repetition for an uplink shared channel transmitted after receiving a contention-free random access (CFRA) message, or a configuration for dropping one or more repetitions of the uplink shared channel. The UE may request the repetition for the uplink shared channel if the configuration information indicates the configuration for requesting repetition. The UE may transmit the uplink shared channel based at least in part on the configuration information. Numerous other aspects are described.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a random access response associated with a random access channel (RACH) procedure. The UE may transmit, based at least in part on receiving the random access response, data indicating a request for coverage enhancement associated with an acknowledgment associated with the RACH procedure. Numerous other aspects are described.

Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE detects one or more conditions are met for transmitting a medium access control (MAC) control element (CE) providing assistance information to a network entity for scheduling. In response to the detection, the UE then takes one or more actions to obtain uplink (UL) resources for transmitting the MAC CE.

An apparatus for wireless communication includes a transmitter configured to communicate with a base station based on a first uplink bandwidth part (BWP) that includes a first frequency subset and that further includes a second frequency subset. The apparatus further includes a receiver configured to receive, from the base station, one or more messages including a frequency hopping indicator that specifies whether a frequency hopping mode is enabled or disabled. The transmitter is further configured to transmit, to the base station, an uplink control channel transmission using both the first frequency subset and the second frequency subset based on the frequency hopping indicator specifying that the frequency hopping mode is enabled or using one of the first frequency subset or the second frequency subset based on the frequency hopping indicator specifying that the frequency hopping mode is disabled.
