  • Patent number: 11444733
    Abstract: Methods, systems, and devices for wireless communications are described. Some systems may support digital post-distortion (DPoD) processing at a base station. In some such systems, a user equipment (UE) may process a data message for transmission, where a resulting signal associated with the data message includes non-linear characteristics that are handled by DPoD on the receiver-side. The non-linear characteristics may cause the signal to leak into out-of-band (OOB) resources, potentially resulting in interference. In some examples, the UE may transmit the data message to the base station in a multi-user system. To support mitigation of non-linear interference on signaling by other UEs, the UE may additionally transmit pilot signals in OOB resources (e.g., in addition to in-band resources) where the non-linearity may be expected to negatively affect other communications. The base station may use the OOB pilot signals to perform channel estimation and interference mitigation.

  • Patent number: 11445445
    Abstract: A wireless device is disclosed that can support carrier aggregation uplink (“CAUL”) communication using a single wideband coupler. A single wideband coupler that can operate or support some or all of the communication bands of the wireless device can be used in conjunction with one or more diplexers and/or filters to measure the power of individual communication bands involved in the transmission process. Further, the use of a wideband coupler and switching network to measure the transmit power from the one or more transmit paths or main paths of a wireless device can reduce the size of a transceiver and reduce the insertion loss attributed to the power measurement components compared to systems that use separate measurement systems for each transmit path. The power measurement system may occur in a separate path in electrical connection with the wideband coupler, which may therefore be termed a coupler path.

  • Patent number: 11444735
    Abstract: Methods, systems, and devices for wireless communications are described. For example, a first wireless device may transmit, via a first beam, a first set of data and a first reference signal associated with the data on a data channel for beam refinement. The first wireless device may further transmit, via a second beam, a second set of data and a second reference signal on the data channel for beam refinement. A second device may receive the first set of data and first reference signal in addition to receiving the second set of data and second reference signal. The second device may transmit, to the first device, beam refinement feedback information for the first beam and the second beam based on receiving the first reference signal and the second reference signal on the data channel. Thus, the first device may refine beams based on a data transmission over a data channel.

  • Patent number: 11438100
    Abstract: Methods, systems, and devices for wireless communication are described for polar coding with rate matching. A transmitter may construct input channels into a polar encoder to provide an information bit vector that does not include punctured or shortened bits. One or more transmission capacity factors may be used in identifying the information bit vector, which may be mapped to one or more of a codeword length of the polar code or a number of transmitted bits in each codeword. A number of different rate matching schemes may be available for transmissions, and may be selected based on one or more polar coding parameters. In some cases, mapping techniques may be used in two or more different rate matching schemes.

  • Patent number: 11405245
    Abstract: Methods and devices are described for polar encoding and decoding control information that has been modulated based on one or more identifiers of the transmitter and/or receiver. Some embodiments describe scrambling sequence design for multi-mode block discrimination on control information blind detection and decoding. Separate scrambling masks may be applied to disparate bit fields within a coded DCI message, wherein each of the scrambling masks is derived from a user equipment (UE)-specific identifier, a UE group identifier, or a base station identifier. Frozen bits of the polar code may be used to encode and transmit hybrid automatic repeat request (HARQ) acknowledgment messaging for early retransmission of unsuccessful downlink messages. A tiered process of UE identification may be employed to improve a balance between early termination of the decoding process and success of the UE identification process.

  • Patent number: 11394497
    Abstract: A user equipment (UE) receives physical downlink shared channel (PDSCH) in a downlink slot as scheduled using a downlink control indicator (DCI). The UE identifies that the downlink slot is part of a group of downlink slots based on the DCI and/or another DCI corresponding to the group. The UE identifies one or more uplink slots at which to transmit hybrid automatic repeat request (HARQ) feedback corresponding to the slots in the group, and transmits the HARQ feedback at one of these uplink slots. If HARQ feedback is not received, a semi-static codebook may prevent HARQ payload size misalignment.

  • Patent number: 11395295
    Abstract: Disclosed are a wireless communication base station device and a division number determination method that improves the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit.
