Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to wireless transfer of sensor information between a station (e.g., a VR headset) and an access point (e.g., a server).

The present application relates to a method and an apparatus for sidelink burst transmission. The method includes: performing a channel access procedure for initiating a channel occupancy for sidelink transmission; transmitting sidelink control information (SCI) to another apparatus within the channel occupancy; wherein the SCI includes an indicator indicating a remaining duration of the channel occupancy; and transmitting sidelink data associated with the SCI to the another apparatus without exceeding the remaining duration of the channel occupancy.

A user equipment (UE) may transmit a configured-grant uplink control information (CG-UCI) to a base station during a channel occupancy time (COT) initiated by the UE in a shared spectrum, the CG-UCI comprising COT sharing information, the COT sharing information indicating, at least, an index value corresponding to a combination of: an indication of an offset to a beginning of a downlink transmission opportunity during the COT; an indication of a duration of the downlink transmission opportunity during the COT; and an indication of a channel access priority class (CAPC) value used by the UE to initiate the COT. The base station may transmit a downlink transmission to the UE within the downlink transmission opportunity and in accordance with the COT sharing information in the transmitted CG-UCI. Apparatuses are also disclosed.

For example, a wireless communication station (STA) may be configured toto transmit a reservation signal over a wireless medium at a reservation signal transmission time, for example, based on a determination that high-priority data of a high-priority Access Category (AC) is queued at the STA. For example, the reservation signal transmission time may be based on an end of a predefined time duration from a start of a contention period. For example, the reservation signal may be configured to indicate a busy Clear Channel Assessment (CCA) to a receiving STA. For example, the STA may be configured to contend the wireless medium according to a high-priority contention policy, for example, after transmission of the reservation signal, to obtain a Transmit Opportunity (TxOP) for transmission of the high-priority data.

A multi-link device using a plurality of links is disclosed. A processor receives, in any one link of the plurality of links, a first physical layer protocol data unit (PPDU) including access category (AC) constraint signaling and a reverse direction (RD) grant from a station which is a transmission opportunity (TXOP) holder or a service period (SP) source, and transmits, in the any one link, a second PPDU to the station in response to the first PPDU on the basis of the AC constraint signaling. The AC constraint signaling indicates whether a traffic identifier (TID) or AC of a frame included in the second PPDU is constrained.

Methods and apparatuses for channel access procedure priority on a sidelink (SL) in a wireless communication system. A method of a user equipment (UE) includes determining a type of a SL channel access procedure before a SL transmission, which is a Type 1 SL channel access procedure or a Type 2 SL channel access procedure, and determining, based on a type of the SL transmission, a channel access priority class (CAPC) when the type of the SL channel access procedure is the Type 1 SL channel access procedure, wherein the CAPC is associated with a parameter p. The method further includes performing, based on the type of the SL channel access procedure and the CAPC, the SL channel access procedure before the SL transmission and performing the SL transmission if the SL channel access procedure is successfully performed.

A UE receives control signaling that indicates that the UE is scheduled to transmit one or more uplink control channel messages on a first component carrier that overlap in a time domain with one or more uplink shared channel messages scheduled for transmission on a second component carrier. The UE resolves a first overlap of uplink control channels having a same priority level, if present, and resolves, after resolving the first overlap, a second overlap of an uplink control channel and at least one uplink shared channel having the same priority level, if present. The UE resolves two or more channels having a different priority level after resolving the first overlap and the second overlap. The UE transmits one or more uplink transmissions including at least one of the one or more uplink control channel messages and the one or more uplink shared channel messages.

Various solutions for handling overlapped transmission opportunities with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive configurations allocating a first transmission opportunity and a second opportunity. The apparatus may determine whether the first transmission opportunity and the second transmission opportunity are overlapped. The apparatus may determine a priority of at least one of the first transmission opportunity and the second transmission opportunity according to a predetermined rule in an event that the first transmission opportunity and the second transmission opportunity are overlapped. The apparatus may perform a transmission according to the priority.

A sequence allocating method and apparatus wherein in a system where a plurality of different Zadoff-Chu sequences or GCL sequences are allocated to a single cell, the arithmetic amount and circuit scale of a correlating circuit at a receiving end can be reduced. In ST201, a counter (a) and a number (p) of current sequence allocations are initialized, and in ST202, it is determined whether the number (p) of current sequence allocations is coincident with a number (K) of allocations to one cell. In ST203, it is determined whether the number (K) of allocations to the one cell is odd or even. If K is even, in ST204-ST206, sequence numbers (r=a and r=N−a), which are not currently allocated, are combined and then allocated. If K is odd, in ST207-ST212, for sequences that cannot be paired, one of sequence numbers (r=a and r=N−a), which are not currently allocated, is allocated.

The disclosed embodiments provide for management of a Wi-Fi network in the presence of a high priority receiver. When a high priory receiver is identified, a portion of the Wi-Fi network that could potentially interfere with the high priority receiver is identified and steps are taken to reduce the probability of such interference. For example, some wireless transmitters may be switched to alternate channels to reduce the probability of interference. By sharing information relating to high priority receivers across a plurality of wireless transmitters, the disclosed embodiments provide for more efficient operation in the presence of high priority receivers when compared to methods that independently detect a high priority receiver at each wireless transmitter.
