  • Publication number: 20210176013
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

  • Publication number: 20210168850
    Abstract: A wireless communication method includes a network node that transmits to one or more communication nodes a set of parameters for selection of a multiple access transmission scheme from a plurality of multiple access transmission schemes, such as an orthogonal multiple access (OMA) scheme and a non-orthogonal multiple access (NOMA) scheme. The network node receives data transmitted by a communication node using the multiple access transmission scheme selected by the communication node. The network node can also transmit one or more sets of parameters for one or more transmission configuration groups or a set of parameters for re-transmission, where the transmission configurations group(s) and the parameters for re-transmission define a multiple access transmission scheme to be selected from a plurality of multiple access transmission schemes.

  • Publication number: 20210160880
    Abstract: Provided are configuration information transmission method and device. The method includes: transmitting configuration information, where the configuration information includes at least one of the following: configuring N sets of data channel configuration information for one frequency domain bandwidth, configuring M sets of control channel resource configuration information for one frequency domain bandwidth, or configuring C sets of measurement reference signal configuration information for one frequency domain bandwidth, where N, M, and C are integers greater than or equal to 1. The above solution resolves the issue of the lack of data transmission between multiple TRPs and a terminal in the related art. Multiple sets of configuration information are configured for one frequency domain bandwidth, such that different configuration information can be used in multi-TRP transmission, thereby realizing data transmission between multiple TRPs and a terminal.
