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.

Methods, systems, and devices for wireless communication are described. In multi-user (MU) multiple-input multiple-output (MIMO) wireless communications systems, a base station may perform signaling to indicate information related to ports assigned to one or more UEs. The base station may also signal information regarding ports shared with other UEs, which the UE may use when performing channel estimation. In some examples, the base station may signal a number of ports used per sub-band to the UE or a number of demodulation reference signal (DMRS) ports used by the UE. The base station may signal a sub-set of a total number of ports that are shared by other UEs overlapping with the resource allocation of the UE. The signaling may indicate a number of combs used by the base station in the resource allocation for the UE.

Logic may enable client devices or access points to relay medium access control (MAC) frames. Logic may extend the range of IEEE 802.11 devices, such as IEEE 802.11ah devices.

An electronic device according to various embodiments can comprise: a housing; a wireless communication circuit located in the housing; a processor operationally connected to the wireless communication circuit; and a memory located inside the housing and operationally connected to the processor, wherein the memory can store instructions such that, when executed, the processor performs camp-on on a cell of a first base station through the wireless communication circuit, receives, from the first base station, information related to a network related to the first base station, identifies a state in which no service is provided from the first base station to the electronic device, and searches for a registered public land mobile network (RPLMN) on the basis of at least a portion of the received information.

Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.

A method for a first device to perform wireless communication and a device supporting same. The method may include the steps of: receiving, from a base station, a time division duplex uplink-downlink (TDD UL-DL) configuration including information related to a UL resource; receiving, from the base station, information related to the start of sidelink (SL) symbols, information related to the number of the SL symbols, and a bitmap indicating one or more slots included in an SL resource pool; and determining the SL resource pool.

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to connect to a base station using a random access procedure. During the random access procedure, the base station may transmit control information and data associated with a random access response (RAR) during an RAR window. The UE may identify a channel quality and may transmit a random access request of a first type to the base station. The base station may receive the random access request and transmit repeating instances of the control information or the data, or both, based on identifying that the random access request is of the first type. The UE may use soft-combining to increase the likelihood of successfully decoding the control information and the data associated with the RAR, and likewise may increase the likelihood of successfully receiving the RAR from the base station.

A method and device are disclosed from the perspective of a User Equipment-to-User Equipment (UE-to-UE) Relay to forward sidelink UE capability information. In one embodiment, the method includes the UE-to-UE Relay receiving a first sidelink UE capability information from a first UE. The method further includes the UE-to-UE Relay transmitting the first sidelink UE capability information of the first UE and a second sidelink UE capability information of the UE-to-UE Relay to a second UE or transmits a combined sidelink UE capability information to the second UE, wherein the combined sidelink UE capability information is derived from the first sidelink UE capability information and the second sidelink UE capability information.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling indicating a configuration for communicating to the UE a random access response of a random access procedure. The configuration may indicate a first quantity of instances of control information associated with the random access response in a set of slots and a portion of the time window configured for the first quantity of instances. The UE may monitor the set of slots for instances of the control information and receive a second quantity of instances of the control information for the UE in a first subset of slots of the set of slots. The second quantity of instances may be less than the first quantity of instances. The UE may combine the instances of the control information from the first subset of slots and decode the random access response based on combining the instances.

During operation, an access point may determine, based at least in part on communication with the electronic device, that an electronic device is in a communication performance category. In response, the access point may provide one or more requests to one or more neighboring access points of the access point, where a given request is for an assessment of communication performance of the electronic device from a perspective of a given neighboring access point. Next, the access point may receive one or more reports associated with one or more neighboring access points with one or more assessments of the communication performance of the electronic device. When the one or more assessments indicate that superior communication performance is unavailable, the access point may provide a notification to a computer that indicates that the electronic device is in a coverage hole in a WLAN.
