Abstract: Improved techniques of include performing random access in an antenna-distributed network include introducing a new parameter, as reduced Tx power indicator, in the RAR of Msg-2 that indicates a reduced total Tx power of all antenna nodes of the antenna-distributed network. When the gNB receives a Msg-1, the gNB determines a subset of the distributed antenna nodes to which the gNB will send the RAR in the Msg-2 with the reduced total Tx power needed to transmit the Msg-2 to only those antenna nodes in the subset. The RAR includes a new parameter indicating the reduced total Tx power used to transmit the RAR to the UE. The UE then uses the value of the new parameter to estimate a pathloss for the Msg-3 and PUSCH transmission.

Abstract: Example embodiments of the present disclosure relate to coordinated positioning via sidelink resource. A first terminal device transmits a first message to a plurality of positioning terminal devices including a second terminal device. The first message indicates sidelink resources for transmitting reference signals from the plurality of positioning terminal devices to the first terminal device. Upon receiving the first message, the second terminal device determines a first sidelink resource for transmitting a first reference signal for positioning the first terminal device from the sidelink resources, and then transmits the first reference signal via the first sidelink resource to the first terminal device. Through this solution, a sidelink-based positioning solution can be implemented. In particular, even in the scenario of being partial coverage or being out of coverage, where at least part of the devices involved in the positioning procedure cannot access the network device, the resource allocation for transmitting RSs can be implemented.

Abstract: A technique includes receiving an uplink grant that indicates a size (M) of uplink resources allocated to the user device sub-band precoder indications; determining a set of uplink sub-band allocation parameters, including at least: a total number of bits (N) for sub-band precoder indications (where N remains constant for different values of M); a number of bits (m) per each of the sub-band precoder indications; and a sub-band size (J) for each of the one or more sub-bands; wherein at least one of the number of bits (m) per sub-band precoder indication and the sub-band size (J) for each of the one or more sub-bands changes or is a different value based on different sizes (M) of uplink resources; decoding each of the one or more sub-band precoder indications; and precoding, based on the one or more sub-band precoder indications, data for transmission via the one or more sub-bands.
