  • Publication number: 20240357573
    Abstract: Reporting capabilities regarding Cross Carrier Scheduling (CCS) with different Sub-Carrier Spacing (SCS) may include generating a message to send to a base station. The message may comprise an indication of a user equipment's (UE's) capability for CCS with different SCS. Based on the UE's capability for CCS with different SCS, a number of unicast downlink control information (DCI) per physical downlink control channel (PDCCH) monitoring occasion per span may be processed to determine scheduled resources for downlink (DL) and uplink (UL) signaling or channels. The DL and UL signaling or channels may be processed using the scheduled resources.

  • Publication number: 20240357642
    Abstract: A user equipment is configured to connect to a base station (BS) over a shared channel subject to channel access operations. The UE receives a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), determines that no downlink (DL) transmissions are detected during a predefined time of the BS-FFP and determines that at least one condition associated with an uplink (UL) transmission is satisfied. When no downlink (DL) transmissions are detected during the predefined time of the BS-FFP and the at least one condition is satisfied, the UE performs a UE-initiated channel access operation. When the UE-initiated channel access operation is successful, the UE performs the UL transmission during the UE-FFP.

  • Publication number: 20240357438
    Abstract: Performing a UE-triggered lower layer-based handover may include performing measurements of source gNB CSI-RS samples associated with a source gNB. Measurements of target gNB CSI-RS samples associated with a target gNB may be performed, wherein the CSI-RS samples associated with the source gNB and the CSI-RS samples associated with the target gNB are transmitted in a burst structure. A subset of the source gNB CSI-RS samples and the target gNB CSI-RS samples may be filtered using a layer 1 or a layer 2 filter. A filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples may be generated. Based on the generated filtered result for each of the subset of source gNB CSI-RS samples and the subset of target gNB CSI-RS samples, determining whether a handover from the source gNB to the target gNB is to occur.

  • Publication number: 20240356705
    Abstract: Approaches are described that enhance the reliability of physical downlink control channel (PDCCH) detection where the PDCCH can be transmitted repeatedly with different beams. The approaches use soft combining where the user equipment (UE) combines the soft bits from each repetition, with the combined soft bits used to jointly decode the PDCCH repetitions. To support the soft combining, the UE needs to buffer the soft bits. Buffering approaches include determining what contributes towards the buffering, including scenarios where one of the linked search sets (SSs) is dropped, what is contributed in a linked SS set pair, how the duration of buffer counting is determined, and how the UE reports its maximum buffer size capability.

  • Patent number: 12127221
    Abstract: This disclosure relates to apparatuses and methods for providing and managing reception feedback for multicast and broadcast services (MBS). A base station (BS) may select and communicate, to a group of user equipment devices (UEs), configuration parameters for MBS communications, such as an indication of an MBS retransmission procedure for an MBS service. The BS may also transmit, to the group of UEs, an MBS data communication. A first UE may receive the MBS data communication, but may determine that the received MBS data communication is corrupted. The first UE may respond by transmitting, to the BS, a negative-acknowledgement (NACK) message. The BS may retransmit the MBS data communication either as an MBS transmission or as a unicast transmission, based on the configuration parameters. The first UE may monitor the appropriate resources to receive the retransmitted MBS data communication, based on the configuration parameters.

  • Patent number: 12127099
    Abstract: A base station may restrict access by a user equipment (UE). The base station broadcasts access restrictions to one or more UE within a cell coverage area of the base station, wherein the access restrictions include one or more predetermined criteria that must be satisfied for a UE to be allowed to camp on the base station. The base station performs a random access channel (RACH) procedure to allow the UE to camp on the base station when the UE satisfies the one or more predetermined criteria.

  • Patent number: 12127176
    Abstract: A reduced capacity (redcap) device may perform initial uplink communications, including transmitting a redcap physical uplink control channel (R-PUCCH), over an initial uplink bandwidth part (BWP) shared with a second device, the initial uplink BWP having a bandwidth (BW) larger than a maximum BW supported by the redcap device and smaller than or equal to a maximum BW supported by the second device. Frequency hopping operation for the redcap device may be supported for the R-PUCCH transmission through frequency division multiplexing and/or time division multiplexing settings for the resources used for the R-PUCCH transmission, and for PUCCH transmission by the second device. Restrictions may be implemented to create a gap for redcap devices to perform RF retuning between a physical RACH transmission and a subsequent physical control channel (e.g. PDCCH) monitoring for random access reception when the frequency gap is larger than the maximum BW supported by the redcap device.

    Abstract: Beam failure recovery (BFR) in a multiple Downlink Control Information (mDCI) mode may include receiving, by a user equipment (UE), a Downlink Reference Signal (DL RS) set from a next generation Node B (gNB). The DL RS set may be associated with a link between the UE and the gNB and indicate beam failure detection (BFD) is to be performed for the link. The BFR may further include performing, by the UE, a beam failure detection (BFD) for the link using the DL RS set, and performing, by the UE, a candidate beam detection (CBD) for the link, the CBD determining a candidate beam for the link by determining a beam having a reference signal receiving power (RSRP) that is larger than an RSRP threshold. The BFR may further include transmitting, by the UE, a beam failure recovery request (BFRQ) indicating the link to the gNB.

  • Publication number: 20240349333
    Abstract: A user equipment (UE), a base station, a baseband processor or other network device can operate to generate a sidelink (SL) communication by sensing an SL channel with a clear channel assessment (CCA) and configuring a gap length based on a subcarrier spacing (SCS) and a cyclic prefix extension (CPE) with a CPE length. The CPE length and the gap length can be based on one or more conditions. The SL communication can then be transmitted in response to acquiring the SL channel.

  • Publication number: 20240348385
    Abstract: A user equipment (UE) is configured with multi-transmission and reception point (multi-TRP) operation. The UE groups capabilities of handling two overlapping physical downlink shared channel (PDSCH) transmissions into a plurality of groups, determining a UE capability of handling two overlapping PDSCH transmissions based on the plurality of groups and transmits the UE capability to a next generation nodeB (gNB) of a 5G new radio (NR) wireless network. The UE also determines if a demodulation reference signal (DMRS) of a physical downlink shared channel (PDSCH) transmission collides with a cell-specific reference signal (CRS) of a long term evolution (LTE) transmission and determines if the CRS originated from a same multi-transmission/reception point (TRP) as the DMRS.

  • Patent number: 12119895
    Abstract: Methods and apparatus provide for a wireless network to enable multiple-transmission reception point (multi-TRP) uplink (UL) time division multiplexed (TDMed) repetition transmission. The network may receive, from a user equipment (UE), beam measurements of downlink reference signals associated with a plurality of UL transmission beams from the UE to the multi-TRP. Based on criteria associated with the beam measurements received from the UE, the network enables the UE for the multi-TRP UL TDMed repetition transmission using the plurality of UL transmission beams. In addition, or in other scenarios, coordination is provided between the network and the UE to improve UL TDMed repetition transmissions when a UE switches between antenna panels.
