摘要:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to operate in an antenna switch diversity mode to transmit an uplink signal according to an antenna switching pattern, the antenna switching pattern comprising switching between a first transmit chain coupled to a first antenna and a second transmit chain coupled to a second antenna. The UE may transmit at least a first portion of the uplink signal using the first transmit chain coupled to the first antenna, the first transmit chain coupled to the first antenna. The UE may transmit at least a second portion of the uplink signal using the second transmit chain coupled to the second antenna, the second transmit chain coupled to the second antenna.
摘要:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.
摘要:
Methods and devices are disclosed for enabling improved performance on a multi-subscriber identification module (multi-SIM) wireless communication device. The wireless communication device may detect transmit activity on a modem stack associated with the first SIM, and detect a communication activity scheduled on a modem stack associated with the second SIM having a higher priority. If the transmit activity on the modem stack of the first SIM will impede the communication activity, the wireless device may identify subframes on the modem stack associated with the first SIM that overlap in time with the communication activity and for each identified subframe, blank symbols that conflict with the communication activity to develop a partially blanked subframe. The partially blanked subframe may be transmitted according to a blanking policy.
