摘要： Techniques of transmitting and receiving HARQ feedback for point to multipoint data packets include using two different PUCCHs for providing ACK/NACK feedback to a sequence of point-to-multipoint (PTM) data packets. For example, when a gNB sends PTM data packets (e.g., as part of a subscription) to subscriber UE's, each UE sends ACK/NACK messages in response over a first PUCCH which has a smaller bandwidth than a conventional PUCCH under which full uplink control information (UCI) may be sent. In some implementations, the ACK/NACK messages are a single bit. In response to a NACK message from a UE, the gNB allocates a second PUCCH to the UE. The UE then send additional details to explain the NACK message. In some implementations, the additional details include an identifier of a missing data (e.g., packet m of n).

摘要： The present subject matter relates to an apparatus. The apparatus includes circuitry being configured for encoding sets of data elements into corresponding larger sets of encoding elements using a rateless erasure coding method, for each subset of one or more encoding elements of the sets of encoding elements determining a set of one or more beams of a multi-antenna system; and transmitting the subset of one or more encoding elements in the set of beams simultaneously.

摘要： When a given user equipment (UE) has a plurality K of cells currently serving it, in various embodiments there is an algorithm for triggering the UE to wirelessly send a cell measurement report. The algorithm utilizes a parameter whose value is dependent on the number K of cells currently in the UE's active set. The UE updates K anytime a new cell is added to, or a serving cell is removed from, the UE's active set. In various examples the parameter is an offset that operates such that for adding a new cell increasing values of K make it more difficult to satisfy the algorithm. One example has the offset's value computed using a slope value provided by the network and a default offset value; another has the offset's value computed using maximum and minimum allowable values of both K and the offset which are provided by the network.
