  • Publication number: 20240147454
    Abstract: Methods and apparatuses are provided in which it is determined that a dynamic scheduled channel and a non-dynamic scheduled channel at least partially overlap in a time domain. It is determined whether the dynamic scheduled channel and the non-dynamic scheduled channel are associated with different transmission and reception points (TRPs). Both the dynamic scheduled channel and the non-dynamic scheduled channel are transmitted or received, in case that the dynamic scheduled channel and the non-dynamic scheduled channel are associated with different TRPs.

  • Publication number: 20230232340
    Abstract: Disclosed are systems and methods for enhancing sounding resource signal (SRS) communications. In some embodiments, power control parameters and/or spatial relation information is determined prior to transmissions of the SRS signal. The determination may include a dynamic determination or a selection of a power control parameter set from a plurality of power control parameter sets. In some embodiments, cross-SRS interference is reduced when multiple transmissions utilize a same resource by applying orthogonal cover codes (OCC) to the resources prior to transmission.

  • Publication number: 20230130150
    Abstract: A User Equipment is disclosed that determines a default Transmission Configuration Indicator (TCI) state in a wireless communication network in a High-Speed Train environment. The UE determines that wireless communication is being carried out in Frequency Range 2 and receives one or more Core Resource Sets (CORESETs) carrying a Physical Downlink Control Channel (PDCCH) with a Downlink Control Information (DCI); that a time offset between reception by the UE of the DCI and a corresponding Physical Downlink Shared Channel (PDSCH) is less than a predetermined time threshold; that the PDSCH is configured with a Single Frequency Network (SFN) scheme; that an option to enable two default TCI states for the UE is not configured; whether the PDCCH is configured with an SFN scheme; and based on a result of determining whether the PDCCH is configured with an SFN scheme, a default TCI state is determined for PDSCH reception.

A method performed by a user equipment (UE) includes receiving, from a base station, downlink control information (DCI) including a sounding reference signal (SRS) resource indicator (SRI) field; and transmitting an SRS based on an SRS resource allocated to the UE in the SRI field. The SRI field indicates a transmission rank and one or more precoding weights based on an SRS set including NSRS SRS resources, where 1?NSRS?8, and an SRI field bit length that is less than a threshold value determined from a maximum number of layers to be transmitted and the NSRS SRS resources.

  • Publication number: 20200177268
    Abstract: Precoding is a technique that may be used in wireless communications when antenna spacing in a multiple-input multiple-output (MIMO) system is smaller than optimum spacing conditions. A precoding system and method are disclosed herein that distributes power among streams to trade-off increased data throughput and complexity of interference cancellation. Distributing power among streams may increase data throughput compared to singular value decomposition (SVD) precoding, but interference may be reduced compared to other methods that result in relatively high interference.
