An exemplary embodiment provides an apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to receive, at a first device, a sub-frame comprising at least one symbol transmitted over a network from a network node, wherein the at least one symbol comprising control information to the first device, and transmit, from the first device, scheduled data towards the network node based on the control information.

A method and apparatus are disclosed. In an example from the perspective of a first device, the first device performs sidelink communication with one or more destinations. The first device receives and/or selects a sidelink grant associated with a sidelink transmission. Responsive to the sidelink grant, the first device selects a first destination of the one or more destinations based upon a report signaling. The first device performs the sidelink transmission associated with the sidelink grant to the first destination.

A radio physical layer protocol data unit (PPDU) sending method includes: obtaining, a radio physical layer protocol data unit (PPDU), wherein the PPDU includes a high efficiency-signal field A (HE-SIG-A) and a high efficiency-signal field B (HE-SIG-B), the HE-SIG-A includes a field indicating a quantity of orthogonal frequency division multiplexing (OFDM) symbols in the HE-SIG-B, and wherein a value of the field indicates one of the following: that the quantity of OFDM symbols included in the HE-SIG-B is greater than or equal to 16, or the quantity of OFDM symbols included in the HE-SIG-B; and sending the PPDU.

The present disclosure provides a method and a device in a UE and a base station for wireless communication. The UE receives a first signaling in a first resource element set and a first radio signal. The first resource element set determines a first information set out of M information sets; wherein M is equal to 2; the first resource element set comprises a positive integer number of resource element(s); any information set of the M information sets comprises a positive integer number of information element(s); any information element in the M information sets is a transmission configuration indication state; any information element of the integer number of information element(s) comprises a first type index and a second type index set, a second type index set comprises one second type index or multiple second type indices. The above method helps reduce overhead for scheduling signaling.

A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.

Disclosed are techniques for receiving reference radio frequency (RF) signals for positioning estimation. In an aspect, a receiver device receives, from a transmission point, a reference RF signal on a wireless channel receives, from a positioning entity, an indication that the reference RF signal serves as a source for a quasi-collocation (QCL) type(s) for positioning reference RF signals received by the receiver device from the transmission point on the wireless channel, measures an average delay, a delay spread, or both the average delay and the delay spread of the reference RF signal based on the QCL type(s), receives, from the transmission point, a positioning reference RF signal on the wireless channel, and identifies a time of arrival (ToA) of the positioning reference RF signal based on the measured average delay, the delay spread, or both the average delay and the delay spread of the reference RF signal.
