摘要： Methods, systems, and devices for wireless communications are described. In some examples, a first UE may receive an indication of first resources from a second UE. In some examples, the second UE may be a UE configured to receive a transmission from a third UE over the first resources. In some such examples, the first UE may transmit, to a fourth UE, a sidelink transmission over available resources that exclude the first resources. Additionally, or alternatively, the second UE may be a UE that received sidelink control information from the third UE indicating the resources for transmission by the third UE to a fourth UE. In some such examples, the first UE may transmit, to the second UE, a sidelink transmission over available resources that exclude the first resources.

摘要： In one aspect, an extended SSB (ESSB) is provided that includes more than four symbols to facilitate UE reception of SSBs. In this aspect, the base station configures an ESSB comprising an SSB including four symbols and an initial symbol preceding the SSB. The base station transmits and the UE receives at least a portion of the ESSB. The UE processes the ESSB. Thus, higher capacity UEs can benefit from additional coding gain in the initial symbol while lower capacity UEs can switch beams to receive back-to-back ESSBs. In another aspect, a UE performs additional behaviors to receive SSBs. In this aspect, the UE receives a first SSB using a reception beam, and the UE determines to maintain the reception beam for a second SSB or to switch the reception beam during a PSS symbol of the second SSB. Thus, lower capacity UEs can also receive back-to-back SSBs.

摘要： This disclosure provides systems, methods and apparatuses for uplink channel transmission for multiple transmit receive points (TRPs). In one aspect, a user equipment (UE) resolves overlapping physical uplink control channels (PUCCHs) in a slot or overlapping PUCCH(s) and PUSCH(s) that are mapped to a same TRP in a multi-TRP scenario and that are mapped to two or more different TRPs in the multi-TRP scenario. For example, in a multi-TRP scenario that includes two TRPs, the UE may eliminate overlap of these uplink channels for each of the two TRPs individually and may additionally eliminate overlap of these uplink channels between the two TRPs.

摘要： A method of wireless communication includes determining, by a communication device, a value of a counter associated with a listen-before-talk (LBT) operation. The method further includes, after determining the value of the counter and during a first portion of a deferral interval associated with the LBT operation, performing a first measurement of a particular duration to determine a first energy value. The method further includes, during a second portion of the deferral interval subsequent to the first portion, performing a second measurement of the particular duration to determine a second energy value. The method also includes determining whether to initiate a contention interval associated with the LBT operation based on the first energy value and further based on the second energy value.

摘要： A method of wireless communication includes receiving, by a user equipment (UE) from a base station, a listen-before-talk (LBT) configuration message indicating whether category 2 (Cat2) LBT operations are enabled or disabled for the UE. The method further includes receiving, by the UE from the base station, a channel occupancy time (COT) message configuring the UE with a COT. The method further includes performing, by the UE, an LBT operation based on the LBT configuration message and based on the COT message.

摘要： Techniques for broadcast channel management on a shared communication medium are disclosed. An access terminal may be configured to identify a subframe number associated with a given subframe based not only on a subframe number indicator but also a reference boundary. Conversely, an access point may be configured to set a subframe number indicator for a given subframe based not only on its subframe number but also a reference boundary.

摘要： Certain aspects of the present disclosure provide techniques for making multi-transmission configuration indicator (TCI) state data scheduling more reliable. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a first signal indicative of a plurality of demodulation reference signal (DMRS) ports. The method may also include receiving, from the BS, a second signal indicative of a first spatial state of a physical channel and a second spatial state of the physical channel. The method may also include communicating data over the second subset and not the first subset, based on which of the plurality of DMRS ports are part of the first subset and which of the plurality of DMRS ports are part of the second subset.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) in communication with a serving base station may identify that the UE is a potential victim of interference from a neighboring base station. The UE may transmit an interference coordination message to the neighboring base station. The interference coordination message may request modification of one or more transmission parameters at the neighboring base station. The neighboring base station may modify its transmission parameters to decrease interference with the UE, and the UE may communicate with the serving base station after transmitting the interference coordination message.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a random access channel (RACH) signature from among one or more RACH signatures associated with a synchronization signal block (SSB). The UE may transmit, to a base station (BS), a RACH communication using the selected RACH signature. Numerous other aspects are provided.
