Provided in the embodiments of the present disclosure are methods for transmitting and receiving an SRS, and related devices. The method includes: receiving indication information transmitted by a base station and used to indicate a PRB bundling size; and transmitting, within at least one PRB bundle, the SRS to the base station, wherein the number of PRBs included in the at least one PRB bundle is equal to the PRB bundling size, and a same precoding is used by PRBs belonging to a same PRB bundle, and the precoding is determined by the UE itself.

Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides techniques for determining timing conditions for uplink control information (UCI) processing by a user equipment (UE).

Disclosed in the present application are a signal transmission method and device. The method comprises: a receiving node receiving a request-to-send signal sent by a sending node; and the receiving node sending, according to the request-to-send signal, an allow-to-send signal to the sending node, the allow-to-send signal comprising beam information concerning N candidate beams.

A method and apparatus for indication of resource ports in a communication system is disclosed. In one embodiment, a method performed by a wireless communication node, includes: transmitting a first message to a wireless communication device, and after a time offset, performing wireless communications scheduled by the first message with the wireless communication device.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of resources, in a set of physical multicast channel symbols, for receiving a first type of reference signal and a second type of reference signal. The UE may receive one or more reference signal transmissions in accordance with the set of resources. Numerous other aspects are provided.

The present disclosure relates to reference signal design methods and devices. In one example method, a first communication device obtains at least one sequence from a subset of sequences in a set of sequences and obtains at least one reference signal based on the obtained at least one sequence. The sequence is phase rotated during its generation, phase rotated in the frequency domain, or cyclically shifted in the time domain based on a constant value Δ.sub.q. The first communication device transmits the reference signal to a second communication device.

Provided are a Multicast Broadcast Single Frequency Network (MBSFN) subframe processing method and apparatus, a base station and user equipment. In the solution, a base station places an MBSFN Reference Signal (RS) in a 0-filling region of an MBSFN subframe for transmission, thus making full use of time frequency resources, and facilitating User Equipment (UE) in performing channel estimation by using the MBSFN RS during reception.

Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may communicate with a base station using multiple receivers and receive an indication from the base station to activate a second bandwidth part of a set of bandwidth parts configured for the UE. In response to the indication, the UE may switch from operating in a first bandwidth part to operating in the second bandwidth part and adjust a quantity of active receivers at the UE based on switching from operating in the first bandwidth part to operating in the second bandwidth part. Additionally or alternatively, the UE may adjust the quantity of active receivers at the UE based on monitoring for downlink grants from the base station.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit sounding reference signal (SRS) repetitions in a subset of slots based on control signaling (e.g., downlink control information) received from a base station. For example, the base station may transmit an inter-slot bitmap to dynamically indicate which slots the UE is to transmit the SRS repetitions. In some examples, the base station may also configure and indicate intra-slot SRS repetitions to the UE to indicate on which symbols in a slot indicated by the inter-slot bitmap for the SRS repetitions. Additionally or alternatively, the base station may transmit a start and length indicator value (SLIV) to indicate the subset of slots in which the UE is to transmit the SRS repetitions based on indicating one or multiple start symbols and lengths for the UE to transmit the SRS repetitions.

An operating method and an apparatus are provided in which state information is received from at least one of a higher layer and a plurality of terminals. A respective allocation resource is determined for each of the plurality of terminals, based on the state information. A respective guard band is determined to be allocated for each of the plurality of terminals, based on the respective allocation resource. Respective resource blocks (RBs) are determined for each of the plurality of terminals, based on the respective guard band. Information about the determined respective RBs is transmitted to respective terminals of the plurality of terminals.
