- FIG. 9 shows the TDD SSW frame format (TDD individual BF), which can also be called TDD SSW frame format for TDD SU BF.
- the initiator can indicate that TDD beamforming training is to be ended after the remaining TDD SSW frame is transmitted with the corresponding responder.
- TDD individual BF since the initiator performs TDD beamforming training with a single user, it is only necessary to use a bit to indicate End of Training in the TDD BF Control field in the TDD SSW frame, as shown in FIG. Show.
- the TDD SSW frame transmitted by the initiator in the same TDD SSW slot will be received by multiple users at the same time. Therefore, it is necessary to indicate to each responder whether to terminate the training.
- two solutions we propose two solutions:
- Solution 1 Introduce an indicator field for each responder to indicate whether or not to terminate training with the responder. For details on the modification of the TDD SSW frame structure, refer to FIG. 1. For each responder, an indication field is introduced in its Responder Info subfield. For example, the indication field may be 1 bit, or multiple bits.
- Solution 2 Unlike solution 1, for each responder, a bit is not introduced to indicate End of Training, but the setting of the Responder ID is used to achieve the indication. Specifically, we assign two Responder IDs to each responder, which is convenient for us to call RID1 and RID2. If the initiator does not want to end training, the value of the Responder ID subfield in the TDD SSW frame uses RID1. If the initiator wants to end training, the value of the Responder ID subfield in the TDD SSW frame uses RID2. In this way, the responder can know whether to end the training by merely identifying the contents of the Responder ID subfield.
- the receiving end when the receiving end does not receive the TDD SSW frame, the receiving end needs to perform receiving scanning on all of its receiving sectors, and stays on each receiving sector for a period of time to increase the probability of receiving the TDD SSW frame.
- the amount of time to stay is set by SectorDwellTime.
- the value of SectorDwellTime is set to [2 ⁇ TXTIME(TDD SSWIndividual)+SBIFS], where TDD SSWIndividual is the time of TDD SSW in TDD individual BF.
- TDD group BF because the number of responders increases, the TDD SSW time will also become longer. Therefore, if the previous setting of SectorDwellTime is used, the probability of receiving the TDD SSW frame at the receiving end may be reduced.
- Solution 1 The value of SectorDwellTime is set to [3or more ⁇ TXTIME(TDD SSWIndividual)+SBIFS], where TDD SSWIndividual is the time of TDD SSW in TDD individual BF.
- Solution 2 Start to set the SectorDwellTime to [2 ⁇ TXTIME(TDD SSWIndividual)+SBIFS], and then if the TDD SSW frame has not been received, then the SectorDwellTime will be gradually expanded (either linear or non-linear) and expanded to a certain extent. After the degree is stopped, or after expanding to a certain extent, it begins to shrink.
