A method, an apparatus, and a computer program product for wireless communication are provided. A base station (BS) may configure a component carrier group for a user equipment (UE). The BS may provide an indication of a spatial relation for one or more sounding reference signals associated with a component carrier of the component carrier group. The UE may receive the indication and may apply the spatial relation to the one or more sounding reference signals across bandwidth parts of component carriers of the component carrier group.

A communication apparatus in the present disclosure comprises an AID generator, a Trigger frame generator, and a wireless transmitter/receiver. When a Trigger Type in a trigger frame is an RA trigger, the AID generator (103) generates, as information for an AID12 subfield, information that is different from an AID. The Trigger frame generator (104) generates a RA variant Trigger frame when the Trigger Type in the trigger frame is an RA trigger, and sets, in the AID12 subfield included in the RA variant Trigger frame, the information output from the AID generator (103). The wireless transmitter/receiver (106) transmits the Trigger frame, generated by the Trigger frame generator (104), to a terminal (200).

Methods and devices are provided that enable configuration of a selected set of electronic devices (EDs) that are allocated the same time-domain resources and either orthogonal or the same frequency interlaces on a same unlicensed channel. Configuring the selected set of EDs in order to align transmission starting points in the unlicensed channel and utilizing blocking symbols for at least some of the transmission starting points, may mitigate mutual blocking during LBT procedures.

A method for receiving downlink data by the terminal in a wireless communication system, includes receiving, from a base station, downlink control information for scheduling a short physical downlink shared channel (sPDSCH) on a short physical downlink control channel (sPDCCH), and receiving, from the base station, downlink data on the sPDSCH based on the downlink control information. Here, the sPDCCH and the sPDSCH are based on a first transmission time interval (TTI)-based radio frame structure, wherein the first TTI-based radio frame structure is shorter in time than a second TTI-based radio frame structure related to (i) a physical downlink shared channel (PDSCH) and (ii) a physical downlink control channel (PDCCH). Further, a number of resource element groups (REGs) consisting of a control channel element (CCE) related to the sPDCCH is smaller than a number of resource element groups (REGs) composed of a CCE related to the PDCCH.

This application provides a method and apparatus for obtaining a resource indication value. The method includes: a terminal receives downlink control information, which includes a resource indication value determined based on a first bandwidth part and indicates a data channel occupying contiguous virtual resource blocks in a second bandwidth part, and sends or receives the data channel, wherein a number RB.sub.start identifying the starting virtual resource block of the contiguous virtual resource blocks, a quantity L.sub.RBs of the contiguous virtual resource blocks, and the resource indication value RIV satisfy following relation: RB.sub.start=└K.Math.RB′.sub.start┘, and L.sub.RBs=└K.Math.L′.sub.RBs┘, wherein K is a positive number and satisfies K≤└N.sub.RB.sup.BWP2/N.sub.RB.sup.BWP1┘, N.sub.RB.sup.BWP1 referring to a bandwidth of the first bandwidth part, and N.sub.RB.sup.BWP2 referring to a bandwidth of the second bandwidth part; and RIV=N.sub.RB.sup.BWP1(L′.sub.RBs−1)+RB′.sub.start when (L′R.sub.RBs−1)≤└N.sub.RB.sup.BWP1/2┘, or RIV=N.sub.RB.sup.BWP1(N.sub.RB.sup.BWP1−L′.sub.RBs+1)+(N.sub.RB.sup.BWP1−1−RB′.sub.start) when (L′.sub.RBs−1)>└N.sub.RB.sup.BWP1/2┘

Provided are a method, device and storage medium for configuring a starting symbol position of an uplink data channel. The method includes: determining a configuration value of a first type parameter set, where the first type parameter set is a set of uplink data parameters; determining a configuration range of a starting symbol position of an uplink data channel according to the configuration value of the first type parameter set; and selecting a starting symbol position of the uplink data channel from the configuration range of the starting symbol position of the uplink data channel, and notifying a receiving end of the selected starting symbol position of the uplink data channel.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may select, from a first path and a second path, a path for an uplink communication associated with at least one of a variable payload size for hybrid automatic repeat request (HARQ) feedback or channel state information (CSI) feedback, wherein the first path is on an uplink of the UE and the second path is on a sidelink of the UE; and transmit the uplink communication on the selected path. Numerous other aspects are provided.

Data channel sending and receiving methods, and an apparatus are disclosed. The network device sends indication information to the terminal, where the indication information indicates that the terminal needs to detect data channel puncturing information. The network device sends the data channel puncturing information to the terminal. The network device sends a data channel to the terminal, where the data channel is punctured at a resource location.

A UE receives DCI in a PDCCH, the DCI triggers reception of AP CSI-RS, and the PDCCH has a first numerology and the AP CSI-RS has a second numerology. The UE determines, when a CORESET is configured on an active BWP of a serving cell for receiving the AP CSI-RS and when the first numerology is the same as the second numerology, a default AP CSI-RS beam for receiving the AP CSI-RS based on a beam used for receiving the CORESET with a lowest ID in a latest monitored slot of the active BWP of the serving cell. The UE determines, otherwise when the first numerology is the same as the second numerology, the default AP CSI-RS beam for receiving the AP CSI-RS based on a QCL assumption of a PDSCH TCI state with a lowest ID on the active BWP of the serving cell for receiving the AP CSI-RS.

A method for dynamically allocating radio resources across a set of virtualized radio access points (vRAPs) in a virtual radio access network (vRAN) includes collecting contextual information across all vRAPs that share a common carrier bandwidth of a physical radio access point. The method also includes mapping, by a radio resource controller according to an internal mapping policy, the contextual information of the vRAPs into an allocation of vRAN slices to the vRAPs, wherein each vRAN slice comprises allocated computing resources and an allocated bandwidth part (BWP) of the common carrier bandwidth, the BWPs being orthogonal across the vRAN slices. The method also includes notifying the vRAPs of the allocated BWP.
