摘要： Certain aspects of the present disclosure provide techniques for a user equipment (UE) to determine channel state information (CSI) to feedback to a base station (BS) in a full-duplex wireless communications system while considering UE-to-UE interference and for the BS to configure the UE to provide the CSI to the BS. In an exemplary method, a UE receives, from a base station (BS) in a full-duplex communications system, a channel state information (CSI) report configuration including at least a first indicator of a first associated set of sounding reference signal (SRS) resources; and transmits to the BS a CSI report including CSI and zero or more second indicators of sets of measured SRS resources.

摘要： Some techniques and apparatuses described herein provide an indication of a result of decoding a two-step random access channel (RACH) message and an action to be performed by a user equipment (UE). For example, some techniques and apparatuses described herein may provide the indication using a UE contention resolution identity-based approach, wherein the contention resolution identity of the UE may be provided in a random access response. Some techniques and apparatuses described herein may use a fallback indicator that indicates the result of decoding and/or the action to be performed. Some techniques and apparatuses described herein may use a random access response (RAR) subheader that selectively omits a random access preamble identifier based at least in part on the result of decoding and/or the action to be performed.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a dynamic indication of a transmission power difference between a reference signal and a downlink shared channel for a full-duplex zone. The UE may determine channel state information (CSI) based at least in part on the dynamic indication of the transmission power difference between the reference signal and the downlink shared channel for the full-duplex zone. The UE may transmit a CSI report that identifies the CSI. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communications are described which provide for efficient backhaul communications and identification of resources for cross-link interference (CLI) measurements and reporting. A common resource pool may be configured in which CLI measurements for resources within the resource pool have a common configuration. When providing information indicating resources that are to be measured for CLI, a bitmap that indicates resources within the common resource pool may be provided with CLI measurement configurations corresponding to the common resource pool configuration. Such a bitmap may be communicated via backhaul connections between neighboring base stations when initiating a CLI measurement. Various described techniques also provide for common configuration for CLI measurements, provide for efficient reporting of CLI measurements, and provide for accurate representation of CLI based on measurements at a victim UE.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may perform channel state information (CSI) measurements on one or more reference signal transmissions from a base station; determine, based at least in part on the CSI measurements, a set of non-zero linear combination complex coefficients for weighting and co-phasing for a linear combination of a plurality of frequency domain basis vectors and a plurality of spatial domain basis vectors; and transmit a CSI feedback, wherein a first part of the CSI feedback includes at least an indication of a number of the set of non-zero linear combination complex coefficients with regard to all layers of a communication link between the UE and the base station. Numerous other aspects are provided.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit, and an enhanced machine-type communications (eMTC) user equipment (UE) may receive, an indicator indicating use of a control region of a carrier for a downlink transmission. The BS may transmit and the eMTC UE may receive, based at least in part on the indicator, the downlink transmission during the control region of the carrier. Numerous other aspects are provided.

摘要： Some techniques and apparatuses described herein allocate and/or transmit a narrower bandwidth value for LTE MTC UEs, such as UEs that operate in a small bandwidth mode using LTE procedures, and allocate and/or transmit a wider bandwidth value for 5G MTC UEs, such as UEs that can perform hopping and/or be allocated resources outside of a legacy bandwidth. For example, the wider bandwidth value may be associated with a non-LTE carrier (e.g., a 5G carrier in a 5G bandwidth) with the same center frequency as an LTE carrier associated with the narrower bandwidth value. Some techniques and apparatuses described herein provide for initial access, signaling, paging, random access, unicast communications, frequency hopping, cell-specific reference signaling, narrowband alignment, and/or other coexistence considerations for LTE MTC UEs operating on an LTE carrier and 5G MTC UEs operating on a non-LTE carrier with a bandwidth that includes the LTE carrier.

摘要： Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) resource configuration and processing enhancements. A method generally includes receiving, from the network, signaling indicating a sounding reference signal (SRS) configuration allocating a plurality of symbols for SRS transmissions within an uplink (UL) subframe, detecting a collision between at least one of the allocated SRS symbols and another type of UL transmission, and taking one or more actions regarding the SRS transmissions, based on the detection of the collision.

摘要： Aspects of the present disclosure relate to techniques for codebook subset restriction (CSR). In some cases, a user equipment (UE) receives, from a network entity, codebook subset restriction (CSR) information. The UE determines, based on the CSR information, a restricted beam set for a plurality of antenna panels, determines precoding matrix indicator (PMI) feedback for the antenna panels subject to restricted beam set, and provides the PMI feedback to the network entity.
