Technical Field

Detailed Description

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application. The terms "first," "second," "third," and "fourth," etc. in the description and claims of this application and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions.

User Equipment (UE) may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems with wireless communication capabilities, as well as various forms of terminals, Mobile Stations (MS), terminal Equipment (terminal device), and so forth.

Referring to fig. 1A and fig. 1B, fig. 1A is a schematic diagram of a transmission mode a provided in an embodiment of the present application, and fig. 1B is a schematic diagram of a transmission mode B provided in an embodiment of the present application. In 3GPP, device-to-device communication is studied in different stages.

Proximity based Service (ProSe): device-to-device communication in Rel-12/13 was studied for the ProSe scenario, which is mainly for public safety class traffic.

In ProSe, HARQ is implemented by an active retransmission, where a receiving end does not perform feedback but a transmitting end performs retransmission actively, and the number of retransmissions is fixed to 4 or another value.

Vehicle to internet (V2X): in Rel-14/15, the Internet of vehicles system is studied for the scenario of vehicle-to-vehicle communication, which is mainly oriented to the traffic of vehicle-to-vehicle and vehicle-to-vehicle communication moving at a relatively high speed.

In V2X, HARQ is implemented by active retransmission, where the receiving end does not perform feedback, but rather the originating end performs retransmission actively, the number of retransmissions is specified by the network device (e.g. transmission mode a) or determined by the user equipment (e.g. transmission mode B), and the number of retransmissions may be 1, 2, or some other value.

Enhanced Device-to-Device (futher Enhancements to LTE Device to Device, FeD2D) for wearable devices: in Rel-14, this scenario is studied for a scenario in which a wearable device accesses a network through a cell phone, and is mainly oriented to a scenario in which the wearable device has low moving speed and low power access. FeD2D does not standardize HARQ.

Based on Long Term Evolution (LTE) V2X, a New air interface (New Radio, NR) V2X is not limited to a broadcast scenario, but is further expanded to unicast and multicast scenarios, and the application of V2X is studied in these scenarios.

Similar to LTE V2X, NR V2X also defines the above two resource grant modes, transmission mode a and transmission mode B. Further, the ue may be in a hybrid transmission mode, i.e. both transmission mode a and transmission mode B may be used for resource acquisition, so that there may be a problem of resource collision.

Unlike LTE V2X, NR V2X introduces feedback-based HARQ retransmissions in addition to feedback-free, user equipment-initiated HARQ retransmissions, and is not limited to unicast communications, but also includes multicast communications.

In an implementation manner of the present application, the method further includes:

and if the second logic channel has no data to be transmitted, the user equipment does not transmit the data, or bit filling is performed on the second logic channel.

In an implementation manner of the present application, if the resource authorization status includes two new transmission resources, the method further includes: the user equipment generates a third MAC PDU by using eleventh data in a thirteenth logical channel, wherein the new transmission resource related to the thirteenth logical channel is different from the new transmission resource related to the transmission mode; and the user equipment stores the third MAC PDU into an HARQ process buffer used by a new transmission resource associated with the thirteenth logical channel, or discards the third MAC PDU.

Step 702: the user equipment determines the transmission mode according to at least one of the following items: the ninth transmission mode, the tenth transmission mode, a ninth QoS attribute, a tenth QoS attribute; the ninth QoS attribute is a QoS attribute of data associated with the third retransmission resource, and the tenth QoS attribute is a QoS attribute of data associated with the fourth retransmission resource.

The ninth transmission mode may be transmission mode a or transmission mode B. The tenth transmission mode may be either transmission mode a or transmission mode B. The ninth transmission mode is different from the tenth transmission mode.

Wherein the ninth QoS attribute comprises at least one of: a seventeenth priority of an eleventh logical channel associated with the third retransmission resource; whether the eleventh logical channel has data to be transmitted or not; an eighteenth priority of the ninth data when the eleventh logical channel has ninth data to transmit.

if the fifth judgment result is retransmission and the sixth judgment result is no retransmission, the user equipment determines that the transmission mode is retransmission related to the third retransmission resource and abandons retransmission related to the fourth retransmission resource;

if the sixth judgment result is retransmission and the fifth judgment result is no retransmission, the user equipment determines that the transmission mode is retransmission related to the fourth retransmission resource and abandons retransmission related to the third retransmission resource;

if the fifth judgment result is that retransmission is not performed and the sixth judgment result is that retransmission is not performed, the user equipment determines that the transmission mode is to give up transmission;

if the fifth determination result is retransmission and the sixth determination result is retransmission, the ue performs step 702.

Further, the user equipment performs data transmission based on the third retransmission resource, including:

if the eleventh logical channel has ninth data to transmit, the ue generates a MAC PDU using the ninth data, and transmits the generated MAC PDU using the third retransmission resource.

Or, the user equipment performs data transmission based on the third retransmission resource, including:

and if the third retransmission resource uses a fifth HARQ and the fifth HARQ cache has fifth data to be retransmitted, the user equipment retransmits the fifth data to be retransmitted by using the third retransmission resource.

and if the transmission mode is retransmission associated with the fourth retransmission resource, the user equipment transmits data based on the fourth retransmission resource.

Further, the user equipment performs data transmission based on the fourth retransmission resource, including:

if the twelfth logical channel has tenth data to be transmitted, the ue generates a MAC PDU using the ninth data, and transmits the generated MAC PDU using the fourth retransmission resource.

Or, the user equipment performs data transmission based on the fourth retransmission resource, including:

and if the fourth retransmission resource uses a sixth HARQ and the sixth HARQ cache has sixth data to be retransmitted, the user equipment retransmits the sixth data to be retransmitted by using the fourth retransmission resource.

In an implementation manner of the present application, if the transmission manner is to abandon transmission, the ue determines to abandon the use of the third retransmission resource for retransmission, and abandon the use of the fourth retransmission resource for retransmission.
