    Abstract: A method of beam recovery request (BRR) transmission is proposed. In a first step of beam failure detection, UE detects a beam failure condition of the original serving beam. In a second step of candidate beam identification, UE performs measurements for candidate beam selection. In a third step of BRR transmission, UE transmits a BRR message to BS upon the triggering condition for BRR is satisfied. In a fourth step of monitoring BS response, UE monitors BS response of the BRR transmission. In one advantageous aspect, the BRR transmission is over dedicated contention-free PUCCH resources, maybe with other uplink control information (UCI). Furthermore, the BRR message indicates the status of one or more configured beams, or the status of one or more identified beams, and reports corresponding beam quality indicators.

    Abstract: A user equipment (UE) receives and decodes a first erroneous transport block (TB) from a base station in a mobile communication network. The UE allocates a first soft buffer having a first buffer size. The first soft buffer is associated with a first HARQ process for storing the first TB. The UE then receives and decodes a second erroneous TB from the base station. The UE allocates a second soft buffer having a second buffer size. The second soft buffer is associated with a second HARQ process for storing the second TB. The UE releases a portion of the first soft buffer to be allocated as part of the second soft buffer. The dynamic buffer allocation method reduces mismatch between rate matching and soft buffer storing when the total number of HARQ processes is small. In addition, more HARQ processes can be supported when the corresponding TB size is small.

    Abstract translation: 用户设备（UE）从移动通信网络中的基站接收并解码第一错误传输块（TB）。 UE分配具有第一缓冲器大小的第一软缓冲器。 第一软缓冲器与用于存储第一TB的第一HARQ过程相关联。 然后，UE从基站接收并解码第二个错误TB。 UE分配具有第二缓冲器大小的第二软缓冲器。 第二软缓冲器与用于存储第二TB的第二HARQ进程相关联。 UE释放要作为第二软缓冲器的一部分分配的第一软缓冲器的一部分。 当HARQ进程的总数小时，动态缓冲器分配方法减少了速率匹配和软缓冲存储之间的不匹配。 另外，当对应的TB大小小时，可以支持更多的HARQ进程。

    Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. In one embodiment, the access information comprises mapping information between the TMGI and the communication group ID.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a first wireless device. The first wireless device receives, from a base station, a configuration of first reference signals on a first time-frequency resource. The first wireless device measures the first reference signals received from the base station to obtain first measurements for a direct path between the base station and the first wireless device. The first wireless device obtains second measurements for an indirect path between the base station and the first wireless device via a second wireless device. The first wireless device selects a communication path from the direct path and the indirect path based at least in part on the first measurements and the second measurements.

    Abstract: Methods are provided to support path selection for a remote UE configured with multipath in a UE-to-network relay. A direct path or an indirect path is set as the primary path. Side information of the indirect path is considered for path selection. A remote UE can select a suitable path by utilizing the side information for path selection to check whether an indirect path can fulfill the QoS requirement of arriving UL traffic. In a network-controlled path selection, the base station can request UE to send side information. The base station indicates the selected path or the change of primary path to the UE via explicit signaling. Each path is identified by a path ID. The path indication is in a granularity of per radio bearer, per QoS flow, per logical channel, or per logical channel group.
