Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may measure a RSRP of a CRS for each of a plurality of neighboring cells. The apparatus may also calculate an interference strength of each of the plurality of neighboring cells based on the RSRP measurement of the CRS for each of the plurality of neighboring cells. Additionally, the apparatus may compare a PDSCH demodulation performance of the UE based on rate matching for a CRS offset associated with each of the plurality of neighboring cells with the PDSCH demodulation performance of the UE based on skipping the rate matching for the CRS offset. The apparatus may also transmit a request for the rate matching or skipping the rate matching for the CRS offset based on the comparison of the PDSCH demodulation performance of the UE.

Abstract: A new radio (NR) bit prioritization procedure that may be executed by a UE and a base station is disclosed, resulting in transmission and reception of modulation symbols having prioritized bits. For example, a transmitter may encode a code block using low-density parity-check code to generate a stream of encoded bits. The transmitter may arrange the encoded bits in one or more modulation symbols according to a relative priority of the encoded bits. The highest priority bits may be located in the most significant bits of the modulation symbol, and therefore be less likely to experience errors. A receiver may receive the modulation symbols and reorder the encoded bits according to the coding scheme based on the relative priority prior to decoding the encoded bits. The prioritization of the bits within the modulation symbols may provide improved block error rates over sequential mapping of encoded bits to symbols.

Abstract: A method for wireless communication at a transmitting wireless device and related apparatus are provided. In the method, the device determines, based on the first parameter associated with a Forward Error Correction (FEC) process and a second parameter associated with a probabilistic shaping process, the transport block (TB) size for a TB associated with a signal to be transmitted, and performs the probabilistic shaping process on a first set of data bits of the signal on the TB to obtain a second set of transmit bits. The TB cyclic redundancy check (CRC) is inserted into the TB before or after the probabilistic shaping process, and the probabilistic shaping process is applied on the TB level across multiple code blocks (CBs) associated with the TB or on the CB level individually inside each CB of the multiple CBs. The device further transmits the signal using the second set of transmit bits.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a throttling indicator for a shared resource associated with a modem at the UE. The CE may determine a configuration of the modem based on a configuration received from a Radio Resource Control layer of the UE. Based on the modem configuration and the throttling indicator, the UE may identify a throttling level to apply to the modem. The UE may adjust the modem configuration for communicating with a base station based on the throttling level in order to reduce resource usage below a usage threshold. By reducing usage of the shared resource by the modem, the UE may have a greater availability of the shared resource to meet the needs of other components of the UE. This may provide an improved user experience at the UE, among other benefits.

Abstract: A user equipment (UE) may obtain a plurality of reference signal received power (RSRP) measurements, each RSRP measurement of the plurality of RSRP measurements corresponding to an antenna port of a plurality of antenna ports associated with the UE. The UE may calculate a path loss and a transmit power for the plurality of antenna ports based on a worst RSRP measurement of the plurality of RSRP measurements, and may transmit a sounding reference signal (SRS) based on the transmit power. This may reduce a likelihood that a network node incorrectly estimates the channel conditions experienced by the UE and may improve the channel estimation capabilities of the network node.

Abstract: Methods, systems, and devices for wireless communications are described Techniques described may be utilized to avoid errors caused by resource allocation calculations, which may be indicated via higher layer signaling and/or determined within DCI. A base station may transmit downlink control information indicating resource allocation types to avoid errors. In other cases, the UE and/or base station may designate a particular resource block group size to avoid the potential errors. The UE and/or base station may calculate a number of resource blocks groups for a bandwidth part and allocate the size of the resource block group based on the calculation. The UE and/or base station may conduct a comparison between a bandwidth part size and a resource block group size to determine whether to designate a different resource block group size to avoid the errors. Similar techniques may be utilized in allocating resources for precoding resource block groups.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain hybrid automatic repeat request (HARQ) information indicating whether the network node is configured to perform a retransmission of decoding information prior to an end of HARQ processes associated with the network node. The UE may receive, for a HARQ process associated with a downlink communication from the network node, a retransmission of a transport block (TB) that is associated with a reserved MCS when full decoding information for the TB is unavailable. The UE may perform, based on a reception of a retransmission, an action to proceed with the HARQ process, to restart the HARQ process, or to terminate the HARQ process, wherein the action is based on whether the network node is configured to perform the retransmission of the indication of the MCS. Numerous other aspects are described.
