  • Publication number: 20240179696
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the proposed techniques provide for a semi-persistent design for communicating rate-split messages from a network entity to multiple user equipments (UEs). The network entity may transmit control information to one or more UEs indicating encoding information for receipt of one or more downlink messages to be communicated during respective downlink occasions, which may be configured for rate-split communications. Thus, a first UE may be made aware of one or more semi-persistent downlink occasions via which respective downlink messages (e.g., respective to each downlink occasion) are to be encoded into a common portion and a private portion. In some cases, the common portion may be common with other downlink messages (e.g., intended for other UEs) and the private portion may be specific to the first UE. The first UE may then decode the rate-split downlink messages according to the encoding information.

  • Patent number: 11997629
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

  • Patent number: 11997549
    Abstract: This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media, for a user equipment (UE) to determine and apply limits to physical downlink control channel (PDCCH) processing in a dual active protocol stack handover scenario. In one aspect, the UE utilizes a joint blind decode capability for both a source cell group and a target cell group to determine whether a total limit for PDCCH candidates to monitor or non-overlapped control channel elements (CCEs) to monitor is applicable. The UE may identify a per cell limit for each configured single transmit receive point (TRP) cell and each multiple TRP cell based on a sub-carrier spacing SCS of the cell and the determination. The UE may include an interface configured to obtain a PDCCH for a slot. The UE may perform blind decoding operations on CCEs up to the per cell monitoring limit for each cell.

  • Publication number: 20240172263
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message indicating one or more communication patterns from a base station. The one or more communication patterns may indicate to the UE to adjust one or more parameters for transmitting an uplink communication during a set of time resources, a set of beams, a set of ports, or any combination thereof. During the resources indicated in the one or more communication patterns, the base station may estimate a cross link interference channel between the base station and a second base station. The one or more communication patterns may indicate a hopping pattern for each subband of a bandwidth part. The base station may configure the UE with a timing advance based on the message.

  • Publication number: 20240171364
    Abstract: Full-duplex communication techniques are described. Some aspects may utilize full-duplex-slot formats, such as may be provided in addition to or in the alternative to uplink, downlink, and flexible slot formats. A full-duplex slot implemented in accordance with a full-duplex-slot format provides a slot in which the frequency band may be used for both uplink and downlink transmissions. Downlink and/or uplink transmissions of a full-duplex slot may occur in overlapping frequency bands or in adjacent frequency bands. A first wireless device may transmit slot signaling comprising one or more full-duplex-slot-indicator parameters. A second wireless device may base one or more full-duplex slot configuration determinations on a full-duplex-slot configuration. The second wireless device may apply one or more full-duplex-slot-indicator-parameter rules with respect to full-duplex-slot-indicator parameters for determining a full-duplex-slot format. Other aspects and features are also claimed and described.

  • Patent number: 11991751
    Abstract: A user equipment (UE) may be configured to generate a preamble of a first message associated with a random access channel (RACH) procedure, such as a two-step RACH procedure. The UE may be further configured to determine an identifier (ID) associated with the UE based on at least one of an ID associated with the preamble or a port index associated with a demodulation reference signal (DMRS). The UE may generate a payload of the first message that indicates the ID associated with the UE. The UE may then transmit the first message to a base station to initiate the RACH procedure. Potentially, the UE may receive a second message from the base station responsive to the first message, and the second message may confirm the ID associated with the UE.

    Abstract: Methods, systems, and devices for wireless communications are described. For example, a method for wireless communications at a wireless device may include determining a rate matching configuration for a first channel (e.g., an uplink channel) associated with a second channel (e.g., a downlink channel). A wireless device may determine rate matching resources of an uplink channel based on the rate matching configuration. The wireless device may determine rate matching resources of a downlink channel based on the rate matching configuration. The wireless device may transmit a first message on the uplink channel or the downlink channel, respectively, where the transmitted channel includes the rate matching resources. The wireless device may receive a reference signal on one or more resources of the downlink channel or the uplink channel, respectively, where the one or more resources of the respective channel correspond to the rate matching resources on the transmitted channel.
