Disclosed are techniques related to wireless communication system in which a network node is allowed to puncture a reference signal (RS) to deliver high priority data (e.g., URLLC data) to a user equipment (UE) that is not currently being served by the network node. In an aspect, the RS comprises a puncturable subset and an unpuncturable subset. In an aspect, the puncturable subset comprises resources of the RS that are allowed to be punctured, and the unpuncturable subset comprises resources of the RS that are prohibited from being punctured. In an aspect, the network node transmits the RS such that unpuncturable subset indicates whether or not the puncturable subset of the RS has or has not been punctured.

Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for performing beam failure recovery involving a secondary cell.

Provided are a method and apparatus for sending data, a method and apparatus for processing data, as well as a network side device and a terminal. The method for sending data includes: performing first predetermined processing on data to be transmitted to obtain a first processing result; concatenating the first processing result with the data to be transmitted to obtain concatenated data; performing second predetermined processing on the concatenated data to obtain processed data; and transmitting a segment of data in the processed data and corresponding to a current data transmission of a network side device.

This application provides an information transmission method and apparatus. The method includes: generating, by a network device, first information; and sending, by the network device, the first information to a terminal device, where the first information is used to instruct the terminal device to detect at least one group common PDCCH on N component carriers CCs, N is a positive integer and is less than or equal to M, M is a quantity of CCs configured for the terminal device, and M is a positive integer. Based on this, after receiving the first information, the terminal device detects the at least one group common PDCCH on the N CCs according to the first information.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to transmit a compact uplink control information (UCI) that identifies one or more parameters associated with a transmission of a physical uplink shared channel (PUSCH) communication in a PUSCH resource unit (PRU). The UE may transmit the UCI in the PRU based at least in part on a semi-static payload construction and resource mapping rule. Numerous other aspects are provided.

A random access configuration information based on a reference SCS may allow for a unified coordinate system used by the base station and UEs that describes the time-frequency resource configuration for a two-step RACH procedure. The apparatus receives, from a base station, random access configuration information for the base station. The apparatus determines a first time duration for a preamble of a first random access message based on the random access configuration information received from the base station and a reference SCS associated with an uplink BWP configured for the first random access message. The apparatus determines a second time duration for a payload of the first random access message based on the random access configuration information received from the base station and the reference SCS. The apparatus transmits the first message to the base station to initiate a random access procedure.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a modified physical downlink control channel (PDCCH) configuration for low tier UEs; receive downlink control information (DCI) configured according to the modified PDCCH configuration; and process the DCI according to the modified PDCCH configuration. Numerous other aspects are provided.

The present application relates to user equipment (UE) assisted uplink resource modification. In one implementation, a UE may determine an upcoming absence of uplink data for transmission on an uplink communication channel to a network entity during a period defined by a configured grant, and transmit a message to the network entity to trigger adjustment of at least one resource associated with the configured grant. In another implementation, a network entity may receive a message from a UE representing an upcoming absence of uplink data on an uplink communication channel during a scheduled period defined by a configured grant, and adjust at least one resource associated with the configured grant in response to receiving the message

Methods, systems, and devices for wireless communications are described. A base station to communicate with a set of user equipments (UEs) in a spatial division multiplexing (SDM) configuration for dynamic spectrum sharing (DSS) communications. One or more first UEs of the set of UEs may communicate via a first radio access technology (RAT), and one or more second UEs may communicate via a second RAT in a multiple-user multiple-input multiple output (MU-MIMO) configuration. The base station may indicate the SDM configuration to one or more of the set of UEs. In some examples, the base station may transmit an indication to the set of UEs which may indicate a set of resources to be used for DSS communications. In some examples, the SDM configuration may specify one or more reference signal patterns for communicating in the set of resources.

A shared control region is provided for enhanced dynamic spectrum sharing between a first radio access technology (e.g., LTE) and a second radio access technology (e.g., NR). The shared control region is resource element mapped according to a resource element mapping for the first radio access technology (RAT) and includes pilot signals for the first RAT. The shared control region also includes control information for a user equipment in the second RAT.
