Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting device may communicate an indication of an updated error vector magnitude (EVM) requirement. The transmitting device may transmit a communication using transmit processing associated with the updated EVM requirement. Numerous other aspects are described.

This application relates to the field of wireless communications, and in particular, to a communication method, an apparatus, and a system in a wireless communications system. In the method, a network device and a terminal device determine M resource element group bundles in a control resource set. The network device sends a control channel on resources corresponding to the M resource element group bundles. The terminal device detects the control channel on the resources corresponding to the M resource element group bundles, where M is greater than or equal to 1. The control resource set includes B resource element group resource element group bundles. By using the method, resource configuration efficiency in a communications system is improved.

The present disclosure relates to a wireless communication system and, specifically, to a method and a device therefor, the method comprising the steps of: obtaining information on a plurality of search space sets and a plurality of groups including parts of the plurality of search space sets; obtaining information on one group for monitoring a PDCCH from among the plurality of groups; and monitoring the PDCCH on the basis of search space sets which satisfy a pre-defined condition from among search space sets corresponding to the one group, wherein the pre-defined condition includes a condition where the number of PDCCH candidates and the number of non-overlapping control channel elements (CCEs) are less than or equal to specific values.

A transmission apparatus comprises an assignment information generator which, in operation, assigns resources on a resource unit (RU) basis to one or more terminal stations (STAs) and generates assignment information that specifies RUs allocated to the one or more STAs; a transmission signal generator which, in operation, generates a transmission signal that includes a legacy preamble, a non-legacy preamble and a data field, wherein the non-legacy preamble comprises a first signal field and a second signal field that carry a set ID and the assignment information, and wherein the set ID identifies one assignment set comprising the one or more STAs and a plurality of assignment indices, and wherein the assignment information comprises a resource assignment indication for each of a plurality of assignment which are referenced by the plurality of assignment indices; and a transmitter which, in operation, transmits the generated transmission signal.

Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARQ) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Provided are systems and methods for adaptive payload extraction and retransmission in wireless data communications. An example method commences with transmitting a network packet to a receiver via a communication channel. The method further includes receiving a further network packet including a further payload. The method continues with determining, based on the payload and the further payload, an error vector. The method includes generating, based on the error vector, a plurality of indices. An index of the plurality of indices corresponds to a portion of a plurality of non-overlapping portions of the payload. The method further continues with selecting, based on the error vector, at least one index from the plurality of indices. The method includes sending, to the receiver via the communication channel, a further network packet. The further network packet includes the selected index and a portion of the payload corresponding to the selected index.

The present disclosure relates to a wireless communication system and, more particularly, to a method and an apparatus therefor, the method comprising the steps of: detecting an SSB in an unlicensed band, the SSB including an index related to a CORESET configuration; determining, on the basis of the index, an RB offset used for identifying the position of a CORESET frequency associated with the SSB; and monitoring the CORESET in the unlicensed band on the basis of the RB offset.

A wireless networking system is provided. The wireless networking system includes a base station device including processing circuitry configured to detect a transmission rate from a portion of a preamble of an incoming packet transmission signal and adapt a radio configuration to receive a remainder of the incoming packet transmission signal at the transmission rate.

Methods, systems, and devices for wireless communication are described. A network entity (e.g., a roadside unit, a relay node, a user equipment (UE), or a base station) may use a network coding indication in a transmission that indicates the transmission is a network coded transmission (i.e., the transmission includes retransmitted packets from UEs in a wireless communications system). The indication may be explicitly or implicitly signaled in control information. For example, control information may include a field that explicitly identifies the network coded transmission. Additionally or alternatively, the control information may implicitly identify the network coded transmission, such as by indicating a format of control signaling or including a special source identifier in the network coded transmission. The network coded transmission may also include one or more network coding parameters that identify parameters of the original transmission.

This application provide a control information transmission method, an apparatus, and a system. One example method includes: A first terminal device receives, from a network device, DCI used for indicating a BWP. A quantity of bits in the DCI is a fixed quantity of bits. The DCI is used for scheduling a physical data channel. The BWP is used to transmit the physical data channel.
