  • Patent number: 11622389
    Abstract: A UE, as a part of a RACH communication procedure, may transmit a first sequence within a first set of resources having a first SCS and a second sequence within a second set of resources having a second SCS greater than the first SCS. The second sequence is transmitted with a cyclic prefix greater than inverse of the first SCS divided by a sequence length of the first sequence. The first sequence is a first PRACH preamble. The second sequence may be a second PRACH preamble, an SRS sequence, or DMRS. The UE may repeat the transmission of the first sequence for a first number of times and repeat the transmission of the second sequence for a second number of times independent of the first number.

  • Patent number: 11617181
    Abstract: Aspects of a multi-stage multi-PDSCH grant are provided which allow a UE to obtain data in a downlink data burst with more scheduling flexibility than single-stage multi-PDSCH grants. A base station provides the UE in a downlink control channel a first portion of downlink control information which indicates a plurality of downlink data transmissions. The UE monitors the downlink control channel for the first portion of downlink control information. Afterwards, the base station sends to the UE a second portion of the downlink control information including parameters for one of the downlink data transmissions. The base station may also send the UE a third portion of the downlink control information including additional parameters for the downlink data transmission. After the UE obtains the portions, the UE decodes the one of the downlink data transmissions indicated at least in part by the first and second portion of the downlink control information.

  • Patent number: 11601967
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a grant scheduling a downlink transmission of a set of configurable downlink transmissions. The downlink transmission may include reference slots corresponding to offset values associated with one or more feedback occasions. The UE may construct a feedback codebook based on a first quantity of slots in the set of configurable downlink transmissions, a second quantity of reference slots in the set of configurable downlink transmissions, and a third quantity of configurable offset values associated with one or more feedback occasions. Based on a size of the feedback codebook, the UE may generate feedback bits for reporting whether the UE successfully received a downlink transmission in corresponding slots. In some examples, the UE may identify a slot with a symbol reserved for an uplink transmission, and skip generating a corresponding feedback bit for the identified slot.

  • Patent number: 11601253
    Abstract: A wireless communication system utilizes a synchronization signal block (SSB) structure to enable beam switching at higher sub carrier spacing (SCS) or uplink transmissions within an SSB. The SSB structure has a first SCS for an SSB transmission and a second SCS for a data transmission. The SSB structure is based on the first SCS and the second SCS, with the SSB structure including at least one gap between SSB symbols or between SSBs. The wireless communication system transmits or receives an SSB based on the SSB structure. A base station may transmit a downlink signal during the gap, for example, where the second SCS is much greater than the first SCS. A user equipment may transmit an uplink signal such as an acknowledgment during the at least one gap. The user equipment or the base station may perform analog beam switching during the at least one gap between SSBs.

  • Publication number: 20230039613
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) scheduling multiple physical uplink shared channel (PUSCH) resources for a set of uplink data messages. In some examples, the scheduled PUSCH resources may overlap with reserved or preconfigured uplink resources. The UE may determine, in accordance with a multiplexing configuration, a multiplexing schedule for multiplexing the scheduled PUSCH resources with the reserved or preconfigured uplink resources. The UE may transmit the set of uplink data messages on one or more of the scheduled PUSCH resources based on the multiplexing schedule. The described techniques may enable the UE to transmit the set of uplink data messages with improved reliability based on reducing a number of collisions between the set of uplink data messages and other uplink signals transmitted on the reserved or preconfigured uplink resources.
