A wireless device receives one or more RRC messages comprising configuration parameters of a cell. The configuration parameters indicate uplink BWPs of an uplink carrier of the cell. The uplink BWPs comprise a first uplink BWP and a second uplink BWP. The configuration parameters further indicate a sidelink BWP of the uplink carrier of the cell. A numerology of the second uplink BWP is different than a numerology of the sidelink BWP. The wireless device activates the first uplink BWP. The wireless device activates the sidelink BWP. The wireless device switches from the first uplink BWP to the second uplink BWP as an active uplink BWP. The wireless device deactivates, based on the switch, the sidelink BWP.

The present technology relates to a communication apparatus and a communication method that permit realization of more reliable communication. Provided is a communication apparatus that includes a control section that performs control such that plural aggregated subframes are sent in a predetermined sequence for each frame included in each of spatially multiplexed streams when a frame is sent to another communication apparatus as plural spatially multiplexed streams. The present technology is applicable, for example, to a communication apparatus included in a wireless LAN system.

A wireless device receives configuration parameters comprising first random access parameters and second random access parameters. The wireless device may initiate, based on the first random access parameters, a first random access process on a first BWP of a primary cell. The wireless device may stop the first random access process in response to triggering consistent LBT failure for the primary cell. The wireless device may switch from the first BWP to a second BWP of the primary cell as an active BWP. The wireless device may initiate a second random access process on the second BWP for consistent LBT failure recovery and based on the second random access parameters.

The present disclosure includes a method, apparatus, and computer readable medium for wireless communications for determining, at a first node, first beam orientation information for a second node to select one or more beams for beam training with a third node, determining, at the first node, second beam orientation information for the third node to select one or more of beams for beam training with the second node, transmitting, to the second node, the first beam orientation information, and transmitting, to the third node, the second beam orientation information.

Aspects of the disclosure relate to wireless communication networks having a capability of controlling the mapping of reference signals onto a carrier based on one or more Doppler parameters. A demodulation reference signal (DMRS) is mapped to a carrier according to a pattern based on one or more Doppler parameters, such as a Doppler frequency and/or a rate of change of channel conditions. In a further example, if an initial transmission of an information packet fails due to a high Doppler scenario, the probability of success of the retransmission may be improved by altering the DMRS configuration to account for the high Doppler scenario. Other aspects, examples, and features are also claimed and described.

A first base station receives resource information from one or more wireless devices. The first base station determines, based on the resource information, combined resource information associated with a first cell. The combined resource information comprises a combined channel busy ratio of a sidelink resource pool. The first base station sends, to a second base station, an information message comprising the combined resource information. The first base station receives, from the second base station, a request message requesting a resource configuration of the first cell for a wireless device. The request message is based on the information message.
