A wireless device determines a discontinuous reception (DRX) pattern for sidelink communication and performs sidelink activity within a DRX ON duration of the DRX pattern. A wireless device may transmit a sidelink discovery message including information about a DRX pattern of the first wireless device and may monitor for sidelink communication based on the DRX pattern. A second wireless device may receive a sidelink discovery message from the first wireless device including information about a DRX pattern of the first wireless device and may exchange sidelink communication with the first wireless device based on the DRX pattern.

Discontinuous reception for sidelink

Methods, systems, and devices for wireless communications are described. In one aspect, a UE may report channel state feedback (CSF) to a network entity based on channel state information (CSI) measurements and CLI measurements. In another aspect, a UE may explicitly report CLI measurements to a network entity. In yet another aspect, a UE may report a signal-to-interference-plus-noise ratio (SINR) to a network entity based on CLI measurements, and the network entity may trigger the UE to perform further CLI measurements on signals received from other UEs based on the SINR. In yet another aspect, a UE may generate a report using CLI measurements based on whether the UE is allocated enough time to generate and transmit the report. In yet another aspect, a UE may identify a suitable priority for reporting CLI to a network entity.

Cross-link interference reporting configuration and payload design

Wireless communication techniques leveraging DMRS sharing patterns are disclosed. A method of wireless communication includes receiving, by a user equipment (UE) device, control information. The control information indicates mapping of uplink transmission parameters to one or more demodulation reference signal (DMRS) sharing patterns. The method further includes sending an uplink transmission to a base station in accordance with a DMRS sharing pattern. The DMRS sharing pattern is selected from among the one or more DMRS sharing patterns based on one or more parameters of the uplink transmission. Other aspects and features are also claimed and described.

Demodulation reference signal sharing pattern selection in a wireless communication system

Techniques are described herein for performing channel estimation for both uplink and downlink channels. Additional reference signals may be allocated or assigned to various resource elements (REs) of a transmission time interval (TTI). The receiving device (e.g., a base station or a user equipment (UE)) may be configured to use the additional reference signals during channel estimation. The use of additional reference signals may improve the accuracy of the channel estimations. In downlink communications, a base station may allocate one or more channel state information reference signals (CSI-RSs) to a port of a UE. In uplink communications, a UE may transmit several sounding reference signals (SRSs) in a group.

Techniques for channel estimation

Apparatus, methods, and computer program products for wireless communication are provided. An example method may include transmitting, to a second network entity, a repetition configuration associated with a first PSSCH transmission and a second PSSCH transmission, where the repetition configuration includes information indicative of a frequency hopping pattern associated with the first PSSCH transmission and the second PSSCH transmission. The example method may further include transmitting, to the second network entity, the first PSSCH transmission including a first instance of sidelink information based on the frequency hopping pattern. The example method may further include transmitting, to the second network entity, the second PSSCH transmission including a second instance of the sidelink information based on the frequency hopping pattern.

Transmission across partitioned resource pools

A user equipment (UE) may be configured to transmit or receive reference signals in flexible symbols that are indicated as used for full duplex communications. The UE may transmit or receive reference signals over frequency resources of a symbol indicated as a flexible symbol, which may configured for uplink or downlink communications, that is also configured as full duplex, which may include frequency resources for both uplink and downlink communications. The UE may determine whether or how to transmit one or more reference signals in a flexible symbol based on at least one of the bandwidth of the uplink resources or the bandwidth of the downlink resources, the frequency positions of the reference signals, or other criteria. A base station may be configured to similarly transmit or receive reference signals in flexible symbols that are indicated as used for full duplex communications.

UE behavior with reference signals in a full-duplex symbol

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration for determining a control channel resource candidate that corresponds to an uplink cancellation indication from a set of control channel resource candidates configured for the UE. The UE may also determine the control channel resource candidate that corresponds to the uplink cancellation indication from the set of control channel resource candidates based on the configuration and may monitor for the uplink cancellation indication in the control channel resource candidate that corresponds to the uplink cancellation indication based on the determining.

Uplink cancellation indication resource determination

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a resource pool, from a plurality of resource pools for physical sidelink feedback channel (PSFCH) communications, based at least in part on a first parameter of a set of parameters. The UE may select a resource block, from a plurality of resource blocks within the resource pool, based at least in part on a second parameter of the set of parameters. The UE may perform a PSFCH communication via the selected resource block. Numerous other aspects are described.

Physical sidelink feedback channel resource selection

Certain aspects of the present disclosure provide techniques that may be used to help enable low latency communications between a user equipment (UE) and a base station (BS) using quick uplink channels that enable a reduced transmission time interval (TTI). An example method generally includes identifying a plurality of slots in a subframe, receiving a resource configuration for an uplink channel, wherein the resource configuration is associated with a first slot of the plurality of slots, determining a resource for transmitting the uplink channel in a second slot of the plurality of slots, wherein the resource is determined based on the resource configuration associated with the first slot of the plurality of slots, and transmitting the uplink channel in the second slot using the determined resource.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may configure a discontinuous reception (DRX) cycle of the first UE for a sidelink connection with a second UE. The UE may identify a mode that specifies whether the first UE is to receive a communication outside of an on duration of the DRX cycle if the on duration is extended due to receiving sidelink control information (SCI) reserving a resource outside of the on duration. The UE may communicate in accordance with the mode. Numerous other aspects are described.

Power consumption optimization under discontinuous reception

Methods, systems, and devices for wireless communications are described. For example, a UE may determine a power control adjustment based on sidelink messages received from other UEs. The UE may transmit, to the other UEs, an indication of the power control adjustment to the other UEs. The other UEs may transmit additional sidelink messages in accordance with the power control adjustment, such that power levels of the additional sidelink message satisfy a threshold. A base station may indicate a power control adjustment to one or more UEs. For example, the base station may receive power control information associated with sidelink communications between a set of UEs. The base station may transmit an indication of a power adjustment parameter for a transmit power level for sidelink messages transmitted between two UEs of the set. The value of the power adjustment parameter may be based on the received power control information.

Power control techniques for sidelink communications

The one or more communication patterns may indicate to the UE to adjust one or more parameters for transmitting an uplink communication during a set of time resources, a set of beams, a set of ports, or any combination thereof. During the resources indicated in the one or more communication patterns, the base station may estimate a cross link interference channel between the base station and a second base station. The one or more communication patterns may indicate a hopping pattern for each subband of a bandwidth part. The base station may configure the UE with a timing advance based on the message.
