Abstract
Certain aspects of the present disclosure provide techniques for channel access. One example method by a wireless node generally includes selecting a mode of operation associated with a configuration for communicating with one or more other wireless nodes, determining a procedure for gaining access to a medium to be used for the communication, wherein the procedure is determined based on the mode of operation, and communicating with the one or more other wireless nodes using the mode of operation after gaining access to the medium based on the procedure.
Claims22
A method for wireless communication by a wireless node, comprising:
- selecting a mode of operation associated with a configuration for communicating with one or more other wireless nodes;
- determining a procedure for gaining access to a medium to be used for the communication, wherein the procedure is determined based on the mode of operation;
- and
- communicating with the one or more other wireless nodes using the mode of operation after gaining access to the medium based on the procedure,
- wherein determining the procedure comprises determining to use a more stringent channel access procedure for communicating:
- (i) on a secondary cell as compared to communicating on a primary cell or a primary secondary cell;
- or
- (ii) using a multi-transmission-reception point communication as compared to using a single-transmission-reception point communication, wherein selecting the mode of operation comprises selecting whether the communication uses the single-transmission-reception point or the multi-transmission-reception point communication with a user-equipment.
An apparatus for wireless communication, comprising:
- one or more memories a memory having executable instructions;
- and
- one or more processors, coupled to the one or more memories, and configured to cause the apparatus to:
- select a mode of operation associated with a configuration for communicating with one or more wireless nodes;
- determine a procedure for gaining access to a medium to be used for the communication, wherein the procedure is determined based on the mode of operation;
- and
- communicate with the one or more wireless nodes using the mode of operation after gaining access to the medium based on the procedure,
- wherein to cause the apparatus to determine the procedure, the one or more processors are configured to cause the apparatus to determine to use a more stringent channel access procedure for communicating:
- (i) on a secondary cell as compared to communicating on a primary cell or a primary secondary cell;
- or
- (ii) using a multi-transmission-reception point communication as compared to using a single-transmission-reception point communication, wherein to cause the apparatus to select the mode of operation, the one or more processors are configured to cause the apparatus to select whether the communication uses the single-transmission-reception point or the multi-transmission-reception point communication with a user-equipment.
