PUCCH collision handling for multi-slot long PUCCH in 5G NR

A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a first parameter. The receiving circuitry is also configured to receive a second parameter. The UE also includes transmitting circuitry configured to perform, based on the first parameter, the first PUCCH repetitions in first multiple slots. The transmitting circuitry is also configured to perform, based on the second parameter, the second PUCCH receptions in second multiple slot. For a case that the first PUCCH repetitions collide with the second PUCCH receptions, a priority for different types of uplink control information (UCI) is applied. Hybrid automatic repeat request-acknowledgment (HARQ-ACK) has a higher priority than a scheduling request (SR) and channel state information (CSI). The SR has a higher priority than the CSI.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a negative acknowledgment (NACK) associated with a downlink communication, and may transmit a channel state information (CSI) report based at least in part on transmitting the NACK associated with the downlink communication. In some aspects, a base station may receive, from a UE, a NACK associated with a downlink communication, and may monitor for the CSI report based at least in part on receiving the NACK. Numerous other aspects are provided.

TECHNIQUES FOR PRIORITIZING CSI REPORTS
20230224007 · 2023-07-13 ·

Techniques are described herein for determining a priority ranking for channel state information (CSI) reports based at least in part on a reliability parameter, a latency parameter, or both of resources allocated to a user equipment (UE). In some wireless communications systems, ultra reliable low latency communication (URLLC) services may be interspersed with enhanced mobile broadband (eMBB) services. The UE may perform a CSI report prioritization procedure to account for reliability parameters, latency parameters or both. In some cases, CSI reporting for resources associated URLLC services may receive higher priority than CSI reporting for eMBB services. The UE may be configured to determine reliability parameters and/or latency parameters based on signaling received from the network or from determining changes to one or more configurations of the UE. In some cases, the priority ranking of the CSI report may be based at least in part on a slot set identifier.

Systems and methods for uplink transmission overlap resolution

This disclosure provides systems, methods, and devices for wireless communication that support resolution of uplink (UL) transmission overlap of communication types having different priorities. In some implementations, a method of wireless communication includes determining, at a user equipment (UE), that a first scheduled UL transmission corresponding to a first communication type having a first priority overlaps with a second scheduled UL transmission corresponding to a second communication type having a second priority. The first priority is higher than the second priority. The method also includes multiplexing at least a portion of the first scheduled UL transmission with at least a portion of the second scheduled UL transmission to generate a third UL transmission. The method further includes transmitting, from the UE to a base station, the third UL transmission. Other aspects and features are also claimed and described.

Communication device and SRS transmission control method
11700611 · 2023-07-11 · ·

Provided are a communication device and an SRS transmission method capable of reducing the possibility of a difference in recognition between the presence or absence of an SRS transmission between a base station and a terminal or of an SRS resource so as to prevent degradation of system throughput. At a terminal (200), a reception processing unit (203) detects control information indicating whether or not to request transmission of a sounding reference signal (SRS), whereupon a transmission signal forming unit (207) transmits an A-SRS by way of control by a transmission control unit (206) on the basis of control information. The transmission control unit (206) determines whether or not to execute SRS transmission on the basis of an “SRS Transmission Execution Rule” and the reception status of trigger information.

20230007518 · 2023-01-05 ·

A method of downlink channel state information (DL CSI) computation and reporting is proposed to support high velocity in new radio (NR) systems. In a first novel aspect, two CSI reference slots are defined. CSI reference slot for CSI measurement is defined for determining which CSI-RS/SSB occasion(s) is used for computing CSI. CSI reference slot for CSI computation is defined for determining the slot where UE assumes the CSI computation should be based upon the channel at that time onwards. In a second novel aspect, UE can be configured with a CSI computation period consisting of one or N slots and can be divided into multiple sub-periods without overlap. UE can be configured to compute and report wideband CSI and subband CSI for the whole CSI computation period and/or for each sub-period.
