  • Publication number: 20230022276
    Abstract: The present disclosure describes various aspects of the implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications. Aspects include methods, apparatuses, and computer-readable medium for one or more of multiple PDCCH search spaces, control resource block (CRB), irregular multiple slots or mini-slots grants, or fast control channel signaling for grant-free uplink (UL). For example, different scheduling entities can each have one or two search spaces defined (e.g., common and/or user equipment (UE)-centric search spaces). Also, CRBs can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs). In addition, irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots. Moreover, signaling can be used to indicate to a UE configured for grant-free UL the portion of the pool of resources available for grant-free UL.

  • Publication number: 20230024493
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may be configured to transmit two or more consecutive transmissions that may be used for demodulation reference signal (DMRS) bundling. If criteria for DMRS bundling are not satisfied, the UE may generate dummy data to transmit during the skipped configured grant occasion, and may maintain phase continuity across the skipped configured grant occasion and any other PUSCHs in a set of uplink transmissions. In some examples, the UE may deprioritize DMRS bundling for sets of PUSCHs during which a PUSCH is to be skipped. If criteria for DMRS bundling are not satisfied, the UE may not maintain phase continuity across the set of PUSCHs, and may refrain from transmitting any data during the CG-PUSCH occasion.

  • Publication number: 20230026760
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor search spaces on a primary cell and an secondary cell in a carrier aggregation configuration. The UE may monitor the search spaces for control information according to a shared search space monitoring configuration. Based on the shared search space monitoring configuration, the UE may identify that the secondary cell is a scheduling cell and the primary cell is a scheduled cell (e.g., cross-carrier scheduling). The UE may monitor control channel candidates of search spaces on the primary cell and on the secondary cell for downlink control information messages scheduling data transmissions with the primary cell. In some examples, the cross-carrier scheduled communications may be configured according to a scheduling configuration, which may include one or more scheduling constraints.

  • Publication number: 20230022440
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for a first transmission of a first service type (e.g., enhanced mobile broadband (eMBB)) and a second transmission of a second service type (e.g., ultra-reliable low-latency communication (URLLC)). The UE may identify a feedback codebook size for the first service type. The UE may multiplex a first feedback codebook having the identified feedback codebook size and generated for the first transmission with a second feedback codebook generated for the second transmission. Multiplexing the first and second feedback codebooks may produce a multiplexed feedback codebook. In some cases, the UE may perform the multiplexing based on a feedback multiplexing condition being satisfied. The UE may transmit the multiplexed feedback codebook in a control channel (e.g., a physical uplink control channel (PUCCH)) or a shared data channel (e.g., a physical uplink shared channel (PUSCH)).

  • Publication number: 20230015013
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently signaling configurations of physical resources and transmission parameters to a user equipment (UE) for small data transmissions (for example, data transmissions in an inactive or idle state). A base station may broadcast or multicast downlink control information (DCI) in one or more control channels that schedules data transmissions in a set of data channels. The base station may then multicast one or more configurations in each of the data channels, and a UE may decode one of the data channels to determine a configuration for a small data transmission. Because the configurations may be transmitted in the data channels in addition to system information or paging information, a base station may have access to sufficient resources to provide suitable configurations to a UE for communications in an inactive or idle state.

  • Patent number: 11558821
    Abstract: Methods, systems, and devices for wireless communications are described. In one example, a user equipment (UE) may be configured to receive a control message scheduling a multicast transmission, and the UE may identify an open loop power control parameter for transmitting acknowledgment feedback responsive to the multicast transmission. The identification of the open loop power control parameter may be based on the transmission being multicast to a plurality of UEs, and in some cases a UE may identify an open loop power control parameter that is different than an open loop power control parameter associated with feedback responsive to unicast transmissions. In various examples, open loop power control parameters may correspond to respective feedback resources (e.g., according to a configuration for a set of open loop power control parameters), or to respective physical resource indicators (e.g., as signaled in downlink control information).
