Aspects relate to techniques for communication between wireless communication devices using ranging channel information obtained by each of the wireless communication devices. For example, a first wireless communication device may obtain first monostatic ranging channel information based on reflected ranging signals received in response to transmission of a ranging signal. In addition, the first wireless communication device may receive ranging feedback information from a second wireless communication device associated with second monostatic ranging channel information obtained by the second wireless communication device. The first wireless communication device may then determine bistatic channel information from the first monostatic ranging channel information and the ranging feedback information and transmit a message to the second wireless communication device based on the bistatic channel information.

Systems and methods for managing a network are disclosed. One method can comprise determining a first modulation rate associated with a network device. A beacon can be transmitted at a second modulation rate, wherein the second modulation rate is greater than the first modulation rate. A user device can be associated with the network device based on the beacon if the user device is configured to support the second modulation rate.

An uplink control channel resource determination method, a terminal, and a network side device are provided, relating to the field of wireless communications. The terminal determines the number N of bits of the uplink control information to be transmitted; the terminal determines, according to a target coding rate and N, the number of first resources; the terminal determines, according to the number of first resources and the number of pre-configured resources, the number of resources actually used; and the terminal uses the number of resources actually used to transmit the uplink control information.

According to one embodiment, a wireless apparatus determines a state of a first wireless link with a first mobile station and a state of a second wireless link with a second mobile station in a first communication mode, and transmits a first signal to the first and the second mobile stations in accordance with the states of the first and the second wireless links. In response to the first signal, the first communication mode is changed to a second communication mode in which the wireless apparatus communicates with the second mobile station via a direct communication between the first and the second mobile stations.

A method can include an integrated circuit device, determining if first communication circuits are operating in a first mode that wirelessly receives data at a first rate or a second mode that wirelessly receives data at a second rate that is lower than the first rate. If the first communication circuits are operating in the second mode, transmitting signals with the second communication circuits at a first power level, and if operating in the first mode, transmitting signals with the second communication circuits at a second power level that is lower than the first power level. In the first mode, X symbols per data bit are received and in the second mode, Y symbols per data bit are received, where X<Y. Corresponding devices and methods are also disclosed.

A receiving station simultaneously receives a plurality of procedure protocol data units (PPDUs) from a sending station on a plurality of channels, where the plurality of PPDUs includes a plurality of media access control protocol data unit (MPDU) sets, and each of the plurality of MPDU sets includes at least a copy of a start MPDU. The receiving station sends a block acknowledgment on one or more channels of the plurality of channels, where the block acknowledgment includes acknowledgment information, and the acknowledgment information indicates acknowledgment of MPDUs successfully received on the plurality of channels and transmission quality of each of the plurality of MPDU sets.

A method and a device in a node for wireless communications. A first node monitors or drops monitoring a first signal in a first resource block; and transmits a second signal in a second resource block. The second resource block corresponds to a first index; the first resource block is reserved for a HARQ-ACK for a bit block set transmitted in a third resource block; when a first condition set is fulfilled, a spatial relation of the second signal is unrelated to the first index; when the first condition set is unfulfilled, the first index is used for determining the spatial relation of the second signal; the first condition set relates to whether the first signal is conveyed in the first resource block. The method above provides an easy implementation of beamforming in a V2X system, which optimizes gains of beamforming and also prevents complicated signaling interaction.

Systems and methods for operating a radio system include configuring a first antenna of a plurality of antennas in a wireless device to operate in a configured mode of a plurality of modes, wherein the plurality of modes include a first mode of operating as a quarter wave for operation in a 2.4 GHz band, a second mode of operating as a half wave for operation in a 5 GHz band, and a third mode of operating simultaneous as a half wave and a quarter wave for operation in both the 2.4 GHz band and the 5 GHz band; and operating a first radio of a plurality of radios connected to the first antenna in the configured mode of the first antenna.

Aspects are provided which allow a UE to manage a number of antennas in adaptive receive diversity (ARD) based on packet error rate (PER). The UE measures a downlink PER and determines a number of antennas for receiving a downlink transmission based on the measured, downlink PER. The UE measures downlink PER during switching from a fallback state to a steady state in an ARD state machine, and the UE changes a size of a fallback window in the ARD state machine based on the measured, downlink PER. The UE also disables switching from the steady state to the fallback state based on the measured downlink PER. As a result, a balance between UE reception performance and power savings is maximized and improved downlink data throughput is achieved.

The present disclosure relates to enabling and disabling of codewords in multi-subframe grants. In particular, dynamic and subframe based enabling/disabling of codewords is enabled even if other control parameters including the resource allocation is performed for multiple subframes. For instance, signal from a scheduling entity to a scheduled entity comprises control information including the resource grant common for multiple subframes and a plurality of codewords for each subframe, and a codeword indication indicating enabling or disabling of one or more codewords for each of the multiple subframes. For each subframe it is determined whether a codeword from the plurality of codewords in said subframes is enabled or disabled according to the codeword indication and/or which codeword is enabled or disabled. The indication of enabling and disabling may alternatively be done by using modulation and coding scheme indicator values which are not associated with a particular modulation and coding scheme.
