In some aspects, a user equipment (UE) may receive a first information element (IE) and a second IE, wherein the first IE indicates whether all UEs that do not support cell-specific reference signal (CRS) muting are barred from a carrier and the second IE indicates whether all UEs that support CRS muting are barred from the carrier; and selectively access the carrier based at least in part on at least one of the first IE or the second IE. In some aspects, a UE may determine whether the UE supports cell-specific reference signal (CRS) muting; and transmit, to a base station, a capability report that indicates whether the UE supports CRS muting. Numerous other aspects are provided.

Abstract: A phase tracking reference signal (PT-RS) may be transmitted to enable a receiver to correct phase noise in wireless communication. A UE scheduled for one PDSCH with DMRS ports in two or more DMRS CDM groups that are associated with two TCI states may be configured for PT-RS using two PT-RS ports. Therefore, rather than limiting PT-RS to a single port, the PT-RS may be transmitted to the UE using two PT-RS ports. The apparatus transmits a capability indication for more than one PT-RS port for receiving a downlink shared channel based on a first TCI and a second TCI. The apparatus receives a configuration for a maximum number of downlink PT-RS ports from a base station.

Abstract: Various aspects related to control channel (e.g., PSCCH) scheduling/prioritizing techniques in wireless communications are described. When a UE may not be able to decode various PSCCH transmissions detected in a subframe, a subset of the PSCCHs may be selected for decoding based on the described methods. In accordance with one aspect, a UE may determine that a total number of PSCCH transmissions in a subframe is greater than a number of PSCCH transmissions that can be decoded within the subframe. Upon such a determination, the UE may select at least one PSCCH transmission in the subframe for decoding based on at least one of: retransmission information, information regarding a transmitting UE associated with the at least one PSCCH transmission, or scheduling priority history associated with a sub-channel carrying the at least one PSCCH transmission. The UE may then decode the at least one PSCCH transmission selected for decoding.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify first set of metrics associated with a radio link monitoring procedure on a radio link and identify a second set metrics associated with a procedure for monitoring whether communications of a first service type or having a first quality of service requirement are supportable. The UE may monitor the radio link based on the first set of metrics to assess for radio link failure and monitor at least a portion of the radio link based on the second set of metrics. The UE may determine that a component of the radio link fails to satisfy the second set of metrics, and the UE may transmit an indication of the determination to the base station.

Abstract: Techniques for wireless communications are described. A user equipment (UE) may initially configure a set of channel estimation parameters for a set of radio frequency spectrum subbands of a bandwidth part (BWP) of a transmission opportunity (TxOP). In some examples, the UE may identify an unavailable radio frequency spectrum subband within the BWP. Based on the identification, the UE may reconfigure the channel estimation parameters to avoid performing unnecessary channel estimation processes on the unavailable radio frequency spectrum subband. As part of reconfiguring the channel estimation parameters, the UE may set log-likelihood ratio (LLR) values of subcarriers associated with the unavailable radio frequency spectrum subband to a null value, thereby experiencing improvements in efficiency and reliability of channel estimation for the BWP.

Abstract: An entity, such as a mobile device or base station, measures downlink position referencing signals (PRS) occasions or uplink position sounding referencing signal occasions for supporting estimating the position of the mobile device. The entity, for example, performs a plurality of positioning measurements from a plurality of consecutive PRS occasions received in a bundle from one or more base stations or from a mobile device. Each PRS occasion may include one or more slots and may be narrowband or non-narrowband. The bundled, e.g., consecutive, PRS occasions may be transmitted with a periodicity that is sufficient to maintain a desired throughput. Moreover, with the use of bundled PRS occasions, power consumption of the mobile device, as well as effects of clock drift and mobile device movement, may be minimized.

Abstract: Methods, systems, and devices for wireless communications are described that support channel quality reporting using random access messages. A user equipment (UE) may receive a random access message from a base station and respond with an indication of channel quality information for a communication link between the base station and the UE. The indication may be generated by a single protocol layer of a control plane protocol stack (e.g., a radio resource control (RRC) or media access control (MAC) layer). The channel quality information may be included in the RRC message or in a header of the MAC layer from the UE. The UE may transmit, to the base station, an indication of identified channel quality information. Upon receiving the response message from the UE, the base station may determine communication parameter(s) (e.g., coding rate, modulation order, number of repetitions of a channel) for future communications with the UE.

Abstract: Some techniques and apparatuses described herein protect components of a user equipment (UE), such as a low noise amplifier (LNA), from internal interference. For example, the LNA may be disconnected from a receive chain during periods of high internal interference, and may be reconnected to the receive chain during periods of low internal interference. Furthermore, some techniques and apparatuses described herein improve performance by adjusting operations of the UE to account for and/or offset increased internal interference due to a receive chain that does not include a surface acoustic wave (SAW) filter to remove unwanted radio frequency signals. For example, one or more operations of a baseband processor may be modified to account for the increased internal interference. Additionally, or alternatively, reporting of channel state information may be modified to account for increased internal interference of the UE. Additional details are described herein.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure a physical channel such as a narrowband physical broadcast channel (NPBCH) to supplement (e.g., or as an alternative to) reference signal measurements when determining a received signal measurement, such as a received signal strength or received signal quality of a cell. A base station may transmit an indication to a UE that identifies the frequency at which a portion of NPBCH transmissions (e.g., reserved fields of a master information block (MIB)) is expected to change from one NPBCH transmission to another. The UE may adjust its utilization of NPBCH for determining the received signal measurement based on the indication. Further, the UE may communicate with the cell based on the determination of the received signal measurement, which are based on the indication.

Abstract: Cell-specific reference signal (CRS)-based unicast physical downlink shared channel (PDSCH) transmission is discussed for multicast-broadcast single frequency network (MBSFN) subframes. When one or more CRS-based transmissions are scheduled during an MBSFN subframe in an MBSFN region of a transmission frame, a transmitter can transmit CRS and CRS-based unicast transmissions when no multicast-broadcast transmissions are present in the MBSFN subframe. The transmitter will signal the intent to transmit such CRS-based transmissions, thus, allowing receivers to monitor for the CRS-based transmissions, or ignore monitoring if the receivers are configured in incompatible transmission modes. Additionally, capable receivers may enable CRS-based channel estimation for those MBSFN subframes in the MBSFN region when CRS-based transmission is activated.
