摘要： Embodiments of a system and method for random access and scheduling request for new radio things sidelink are generally described herein. In some embodiments, a nUE (network user equipment) schedules a RA (random access) resource in a control channel. The nUE decodes a TAS (transmitter resource acquisition and sounding) payload, received from a wUE (wearable user equipment) in a PRB (physical resource block) addressed to a RA-ID (random access identifier) associated with the nUE. The nUE encodes, in response to decoding the TAS payload, a RAS (receiver resource acknowledgement and sounding) payload in the PRB. The nUE decodes initial access content received via a data channel from the wUE, the initial access content including a pro posed temp ID (temporary identifier) for addressing the wUE. The nUE encode, in response to the initial access content, an ACK (acknowledgement), addressed to the wUE, to accept initial access of the wUE.

摘要： A base station is capable of unifying a single-user MIMO scheme with a multi-user MIMO scheme by receiving a Rank-1 CQI values from one or more subscriber stations. The base station also receives preceding vectors from the subscriber stations, and then determines which of the subscriber stations has a best Rank-1 CQI value. The base station then determines a beam forming matrix to use based at least in part on the vectors received from the subscriber station having the best Rank-1 CQI value. The base station then broadcasts data to the subscriber station using the beam forming matrix corresponding to the subscriber station having the best Rank-1 channel quality indicator to implement single-user MIMO in one or multiple streams to that subscriber station, or to the subscriber stations having the best Rank-2 channel quality indicators to implement multi-user MIMO in multiple streams.

摘要： A beam selection method in open loop MU-MIMO is disclosed, for an asymmetric antenna configuration. The proposed beam selection method employs limited feedback, as compared with single-user closed-loop MIMO and multiple-user closed-loop MIMO, in which the base station requires channel state information (CSI). The multi-user MIMO beam selection method selects the portion of beams from candidate beams for data transmission, meaning that the base station is training M beams. From this, the subscriber station selects N beams from the total M beams, with N≦M.
