A user equipment (UE) is configured to receive message 3 (Msg3) transmissions. The UE receives a system information block (SIB) transmission from a base station of a wireless network, receives a downlink control information (DCI) transmission scheduling a message 2 (Msg2) transmission from the base station, receives the Msg2 transmission including an uplink (UL) grant for a message 3 (Msg3) initial transmission from the base station, determines the number of repetitions for the Msg3 initial transmission based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission and determines a frequency hopping (FH) type and FH pattern based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission.

Enhancement of message 3 for RACH procedure

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.

Inter-device communication

A UE may transmit a message comprising information regarding one or more physical random access channel (PRACH) capabilities of the UE to a base station (BS). The UE may then receive, from the BS, signaling comprising an indication of one or more configured PRACH formats supporting the one or more PRACH capabilities. Next, the UE may transmit, using the one or more configured PRACH formats, one or more preambles to the BS in a random access (RACH) procedure. Accordingly, the UE may receive a random access response (RAR) from the base station and further, in response to receiving the RAR, establish a connection with the BS.

Physical random access channel enhancements in new radio

Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within it prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.

Power saving sensing for reduced sensing UES using resource re-evaluation and resource pre-emption

Systems and methods for sidelink (SL) resource pool resource use by a user equipment (UE) are disclosed herein. In some embodiments, when the UE performs contiguous partial sensing in addition to periodic partial sensing, the UE performs one of resource selection and resource re-evaluation based a size of a time gap between a slot where the UE has SL data and a first slot of periodic-based candidate slots within a resource selection window. In other embodiments, the UE performs contiguous partial sensing without additional periodic partial sensing in the case where a packet delay budget (PDB) for the SL data is greater than a threshold. In some embodiments, the UE performs periodic partial sensing for resource re-evaluation and/or resource pre-emption according to a set of periodicity values P(and optionally period definition data K). Restrictions on the use of random resource selection by the UE are also described.

Procedures of sidelink resource pool resource use with reduced sensing

Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for a network to use Doppler shift pre-compensation values for communicating Tracking Reference Signal (TRS) to a user equipment (UE) and for implementing mechanisms for triggering the UE to measure the Doppler shift pre-compensated TRS. Some aspects of this disclosure relate to a base station including a processor that determines a Doppler shift pre-compensation value associated with the UE in response to determining that the UE is moving with a speed greater than a threshold. The processor further generates an aperiodic Tracking Reference Signal (AP-TRS) or a semi persistent TRS (SP-TRS) for the UE. The AP-TRS or the SP-TRS is decoupled from a periodic TRS (P-TRS). The processor further transmits the AP-TRS or the SP-TRS to the UE. The AP-TRS or the SP-TRS can be used for time and frequency synchronization.

Tracking reference signal (TRS) enhancement with doppler shift pre-compensation

Some embodiments include an apparatus, method, and computer program product for enhanced Hybrid Automatic Repeat Request (HARQ)-ACK in a fifth generation (5G) wireless communications system. A user equipment (UE) can receive, during a HARQ-ACK window, a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission corresponding to a SPS PDSCH release. The UE can generate a Hybrid Automatic Repeat Request (HARQ)-ACK information bit corresponding to the reception. The UE can be configured with an offset value, k, and a length, l, of the HARQ-ACK window associated with an uplink transmission slot n, of a Physical Uplink Control Channel (PUCCH) transmission, and determine a starting slot of the HARQ-ACK window as n-k. When a corresponding valid uplink transmission slot is not available, the UE can transmit the HARQ-ACK information bit in the uplink transmission slot n of the PUCCH transmission.

Method for enhanced HARQ-ACK feedback in wireless communications

Apparatus and methods are provided to for a user equipment (UE) to report channel state information (CSI) to a base station. The UE sends UE capability signaling to a base station to indicate support of a codebook for high speed scenarios. The UE processes configuration information from the base station for CSI reporting using the codebook. The configuration information indicates measurement resources for one or more downlink (DL) channel. The UE measures a channel response and interference using the measurement resources, generates CSI feedback using the codebook for at least one ray from the base station to the UE, and reports the CSI feedback to the base station.

Predictive CSI enhancements for high speed scenarios

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration for determining a control channel resource candidate that corresponds to an uplink cancellation indication from a set of control channel resource candidates configured for the UE. The UE may also determine the control channel resource candidate that corresponds to the uplink cancellation indication from the set of control channel resource candidates based on the configuration and may monitor for the uplink cancellation indication in the control channel resource candidate that corresponds to the uplink cancellation indication based on the determining.

Uplink cancellation indication resource determination

To support inter-cell multi-TRP operation, disclosed are embodiments that provide a beam indication for the common signals, e.g., signals transmitted and scheduled by some CSS. The disclosed embodiments provide inter-cell multi-TRP with or without serving cell change. In addition, some embodiments provide for switching between inter-cell multi-TRP and intra-cell multi-TRP.

Beam indication for inter-cell multiple transmission and reception (multi-TRP, MTRP) operation

Provided is a method for a base station, includes: generating, for transmission to at least one UE, control information associated with SRS transmission, wherein the control information indicates an SRS band including a plurality of RBs for the SRS transmission, the control information indicates a first subband for a first UE and a second subband for a second UE in a same SRS band for an SRS transmission occasion; receiving, from the at least one UE, SRS on a plurality of SRS transmission occasions according to the control information, wherein a location hopping parameter is applied to the plurality of SRS transmission occasions, wherein a first starting location of the first subband for the first UE on a first SRS transmission occasion and a second starting location of the first subband for the first UE on a second SRS transmission occasion are determined based on the location hopping parameter.

Frequency hopping enhancement for partial frequency sounding

In an example method, a user equipment (UE) device receives a plurality of Synchronization Signal Block (SSB) beams transmitted by base stations (BSes) during discovery burst transmission windows (DBTWs). For each of the SSB beams, the UE device determines an index value of the SSB beam (l) within a respective one of the DBTWs, and determines a value Z=lmod N, where Nrepresents a maximum allowable number of SSB beams transmitted by each of the BSes during a single DBTW. The UE device determines whether two or more of the SSB beams are quasi co-located based on the values Z for the SSB beams, and processes wireless signals received from the BSes based on the determination.

Technologies in multi-PDSCH transmission in a wireless network

Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a single CSI-RS reporting configuration for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The single CSI-RS reporting configuration may include a plurality of CSI-RS resource sets. Each of the plurality of CSI-RS resource sets may include a plurality of CSI-RS resources. At least one of the plurality of CSI-RS resource sets may include CSI-RS resources that correspond to the first TRP or the second TRP. A CSI measurement communication received from the UE may be decoded. The CSI measurement communication may be based on the single CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

CMR and IMR configuration enhancement for multi-TRP CSI-RS reporting

Aspects are described for a user equipment (UE) comprising a transceiver and a processor communicatively coupled to the transceiver. The UE is in a multi-TRP mode. The processor is configured to receive a configuration message, a BFD configuration, and a BFR configuration. The UE switches to a single-TRP mode upon receiving the configuration message. The processor is further configured to update a first BFD procedure based on the BFD configuration and update a first BFR procedure based on the BFR configuration. Finally, the processor is configured to perform the updated first BFD procedure and the updated first BFR procedure for the first TRP responsive to a result of the updated first BFD procedure.
