  • Publication number: 20220303920
    Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

  • Publication number: 20220295506
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first cell associated with a first radio access technology (RAT) and a first radio frequency spectrum band that conflicts with a second slot format configuration for a second cell associated with a second RAT and a second radio frequency spectrum band during at least a portion of a transmission time interval (TTI). The UE may determine that the first cell has a priority over the second cell, based on the configured slot formats or based on the radio frequency bands, and may drop a communication on the second cell based on the identified priority. The UE may then communicate during at least a portion of the TTI on the first cell while the UE drops a communication on the second cell.

  • Publication number: 20220231787
    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.

  • Publication number: 20220225146
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a first energy level of a demodulation reference signal (DMRS). The UE may measure a second energy level of at least one of a tracking reference signal (TRS) or a synchronization signal block (SSB). The UE may determine, based at least in part on the first energy level and the second energy level, a DMRS signal-to-noise ratio (SNR). The UE may perform, based at least in part on the DMRS SNR, channel estimation for a physical channel associated with a communication to determine an estimated channel. The UE may perform, based at least in part on the estimated channel, demodulation processing for the communication. Numerous other aspects are described.

  • Publication number: 20220190958
    Abstract: Methods, systems, and devices for encoding and decoding are described. To encode a vector, an encoder allocates information bits of the vector to channel instances of a channel that are separated into groups. The groups may vary in size and allocation of the information bits is based on a base sequence of a given length. During decoding, a decoder assigns different bit types to channels instances by dividing a codeword into a plurality of groups and assigning bit types to channel instances of the plurality of groups using the base sequence.

  • Publication number: 20220078665
    Abstract: Methods, systems, and devices for wireless communication are described that provide for generation of an encoded transport block (TB) that includes a number of systematic code blocks (CBs) and a number of parity CBs. The systematic CBs may be transmitted to a receiver, and the receiver may attempt to decode the systematic CBs. In some cases, one or more parity CBs may be transmitted with the systematic CBs, and the systematic CBs may be successfully decoded even in the event that one or more of the systematic CBs are not successfully received. In some cases, a receiver may provide feedback that requests that additional CBs be transmitted to decode the systematic CBs that were received, and it is not necessary to retransmit the missing systematic CBs. In some cases, a quantized value of a number of additional CBs needed to decode the TB may be transmitted.

  • Publication number: 20220078710
    Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to reference signal (RS) designs that allow for tracking loop updates and paging of UEs using various RSs. One example method includes identifying reference signal (RS) monitoring occasions for a user equipment (UE) in an idle or inactive mode; and transmitting, to the UE, reference signals in the identified RS monitoring occasions, the RS monitoring occasions being associated with RS for tracking purposes and RS for an indication the UE is to wake up to process additional signaling.

  • Publication number: 20220070807
    Abstract: A device may selectively listen for a tracking reference signal (TRS) during connected mode discontinuous reception (CDRx) based on whether the device is to switch between repeaters of a base station (such as during travel). A device may determine whether the device is in a high speed train (HST) scenario (such as based on a difference in frequency errors generated using a synchronization signal block (SSB) and generated using a TRS, based on a trajectory of a frequency error or a frequency error difference over time, based on instantaneous frequency errors, etc.). When the device is in a HST scenario, the device listens for a TRS during CDRx, and the device generates a frequency error using the TRS. When the device is not in a HST scenario, the device prevents listening for a TRS during CDRx (with a SSB received during CDRx to be used to generate a frequency error).

  • Publication number: 20220053512
    Abstract: A user equipment (UE) receives, from a base station, a message including at least one reporting configuration and resource configuration for a number of channel state information-interference measurement (CSI-IM) resource patterns associated with a first radio access technology (RAT). Each of the configured CSI-IM resource patterns corresponds to a time and frequency location in a resource block of a neighbor cell associated with a second RAT. The UE transmits one or more CSI reports based on the reporting configuration(s) and the resource configuration(s).
