IPC: H04W72/10
Filed: 2020-04-20
Abstract: For SL resource allocation, the Rx UE based sensing and resource allocation mechanism can be applied to improve the reliability and reduce the overall latency, which can work independently or jointly with Tx UE based sensing and resource allocation mechanism. Rx UE performs sensing based on SCI decoding of the other UEs' SCI and measure RSRP on the DMRS of the PSCCH and/or the associated PSCCH/PSSCH. If the reserved resource (s) indicated in SCI from the peer Tx UE are same or overlapping with the sensing resources, the Rx UE will determine whether the reserved resources are acceptable based on sensing results derived from the measured RSRP results and a threshold. Rx UE will indicate acceptability of the reserved resources to Tx UE. The threshold for comparison with RSRP results may be determined based on the function of the priority level indicated in SCI by the other UEs and the priority level indicated in SCI from the peer Tx UE.

Abstract: Disclosed are a large-scale MIMO beam-domain robust precoding transmission method and system. The method is based on a refined sampling steering vector matrix from a base station side and a user side and takes into account the impact of channel aging caused by mobility; the obtained channel state information is refined beam-domain posterior statistical channel information including the mean channel value and variance information. In the present invention, the base station uses the refined beam-domain posterior statistical channel information to carry out robust precoding transmission; the channel model that is used and the refined beam-domain posterior statistical channel information relies on is based on the channel model that uses the steering vector matrix corresponding to a refined sampling space. The statistical channel information used is more sufficient and accurate, which can solve the universal problem of large-scale MIMO for various typical mobile scenarios under a limited antenna size, and obtain high spectral efficiency. The proposed robust precoding design uses the sparsity of the beam-domain channel and the structural features of the sampling steering vector matrix, which can greatly reduce the computational complexity.

Abstract: Beam failure recovery (BFR) in a multiple Downlink Control Information (mDCI) mode may include receiving, by a user equipment (UE), a Downlink Reference Signal (DL RS) set from a next generation Node B (gNB). The DL RS set may be associated with a link between the UE and the gNB and indicate beam failure detection (BFD) is to be performed for the link. The BFR may further include performing, by the UE, a beam failure detection (BFD) for the link using the DL RS set, and performing, by the UE, a candidate beam detection (CBD) for the link, the CBD determining a candidate beam for the link by determining a beam having a reference signal receiving power (RSRP) that is larger than an RSRP threshold. The BFR may further include transmitting, by the UE, a beam failure recovery request (BFRQ) indicating the link to the gNB.
