Abstract: Described is a method and device for detecting a DTX state at a UCI receiver in a wireless communication system. The method comprises receiving a linear block encoded signal on an uplink at said UCI receiver and processing the received signal after resource element (RE) demapping to generate a soft bit sequence s. The method includes selecting a plurality of bits in said generated soft bit sequence s as comparison bits and comparing said selected comparison bits to corresponding bits in a reconstructed soft bit sequence r. The reconstructed soft bit sequence r is generated from a plurality of bits selected as reconstruction bits in said generated soft bit sequence s. A comparison or correlation metric is determined between the comparison bits and the corresponding bits in the reconstructed soft bit sequence r, and a determination is made of the occurrence of a DTX state by evaluating the determined comparison or correlation metric.

Abstract: Described is a method and device for detecting a discontinuous transmission (DTX) state or a partial DTX state at an uplink control information (UCI) receiver in a wireless communication system. The method comprises receiving a linear block encoded signal on an uplink (UL) at said UCI receiver and processing said signal after resource element (RE) demapping to obtain a soft bit sequence. The soft bit sequence is then transformed into multiple sub-sequences. Correlation metrics are determined for two or more of the multiple sub-sequences or two or more sub-sequence groups derived from the multiple sub-sequences or sequence segments derived from the sub-sequence groups. Then, a determination is made if a DTX state has occurred by evaluating the determined correlation metrics.

The resource selection method includes: initializing at least two resource pools, wherein each resource pool corresponds to one carrier; excluding an expected-busy resource from each resource pool associated with a resource of which channel signal strength is greater than a comparison threshold during a sensing period; determining whether remaining resources of a candidate resource pool meet a criterion for stopping resource exclusion, wherein the candidate resource pool comprises a portion of or all the resource pools, and the criterion comprises that a criteria parameter of the candidate resource pool is greater than or equal to a preset threshold of the criteria parameter; selecting a resource subset from the remaining resources of the candidate resource pool when the criterion is met, and otherwise incrementing the comparison threshold.

Abstract: Described is a method of decoding a physical sidelink shared channel (PSSCH) involving physical sidelink control channel (PSCCH) resource grid search space reduction, timing offset (TO) estimation, and reference symbol identification. Resource grid search space reduction may include identifying resource blocks (RBs) having a signal power below a first threshold such that said RBs can be excluded from further processing. Search space reduction may additionally or alternatively include identifying RB pairs where a difference in signal power between the RBs comprising each pair of RBs is above a second threshold and excluding any such said RB pairs from further processing. TO compensation may include circularly correlating TO-compensated received DMRSs and their corresponding local DMRSs to obtain energy or power profiles.
