Description
Technical Field
The present invention relates to the field of communications, and in particular, to a cooperative transmission method and a related apparatus.
Background
In a wireless communication system, after a certain serving cell is connected to a network, a User Equipment (UE) needs to measure a cell adjacent to the serving cell while communicating with a base station, so as to select a suitable cell for handover and meet a mobility requirement. According to different measurement objects, the measurement is divided into common-frequency measurement, different-frequency measurement and different-system measurement. The same-frequency measurement means that the current service cell of the UE and the target cell to be measured are on the same carrier frequency point; the pilot frequency measurement means that the current service cell and the target cell of the UE are not on the same carrier frequency point; the inter-system measurement means that the target cell and the current serving cell belong to different systems. When the UE performs inter-frequency/inter-system measurement, it needs to adjust its radio frequency channel to the frequency point of the target cell for measurement. During the measurement, there may be an interruption to the data transmission of the current serving cell, so the network needs to configure a measurement interval (i.e., measurement gap) for the UE to perform inter-frequency/inter-system measurement.
Due to different hardware capabilities, some UEs need to measure gap when performing inter-frequency/inter-system measurement, and some UEs do not. The UE in a connected state measures the quality of a service cell, when the quality of the service cell is lower than a certain threshold, the pilot frequency/different system measurement is triggered, the UE executes the pilot frequency/different system measurement at corresponding time according to the measurement gap configuration information, and the base station does not schedule the UE during the gap measurement.
And multi-user cooperation, namely, data is transmitted to the base station through cooperation among a plurality of UEs, so that the data transmission reliability or throughput rate of a single UE is improved. In transparent cooperative transmission, since the cooperative UE is not perceived by the base station, when the cooperative UE assists the source UE to transmit data to the base station, traffic collision may be caused by scheduling by the base station, so that reliability of data transmission is reduced.

In order to better understand the cooperative transmission method provided in the embodiments of the present application, a brief description of transparent cooperative transmission is first provided below.
Referring to fig. 1, fig. 1 is a schematic diagram of transparent cooperative transmission according to an embodiment of the present disclosure. As shown in fig. 1, the cooperative transmission method includes an active UE, a cooperative UE, a network device, and the like. Here, the network device is taken as a base station for explanation, and multi-user cooperative transmission, that is, data is transmitted to the base station through cooperation among a plurality of UEs, so as to improve the reliability or throughput of data transmission of a single UE. The user equipment assisting in data transmission is referred to as a cooperative UE, and the assisted user equipment is referred to as a source UE. Data can be transmitted between the source UE and the cooperative UE in a short-distance wireless communication mode, such as sidelink and Wi-Fi Direct.
In cooperative transmission, if the base station does not know the cooperative relationship between the source UE and the cooperative UE, that is, the base station does not perceive that the cooperative UE helps the source UE to transmit data, transparent cooperation is performed. Before cooperative transmission, a source UE needs to send its C-RNTI (Cell-radio network temporary identifier, Cell-RNTI) to a cooperative UE, namely the source C-RNTI in FIG. 1; in transparent cooperative transmission, source UE firstly sends data to cooperative UE, then the source UE and the cooperative UE send the data of the source UE to a base station together, and the data of the source UE sent by the cooperative UE to the base station is scrambled by using C-RNTI of the source UE, so that for the base station, only the source UE is perceived to send the data to the base station.
In the embodiment of the present application, the source UE may be understood as source user equipment, and the cooperative UE may be understood as cooperative user equipment.
Referring to fig. 2, fig. 2 is an interaction diagram of a cooperative transmission method according to an embodiment of the present application. As shown in figure 2 of the drawings, in which,
s201, the cooperative UE acquires the cooperation information.
The cooperative UE may obtain the cooperation information from the base station, and the cooperation information may include configuration information of the first measurement gap, where the configuration information of the first measurement gap is the configuration information obtained by the cooperative UE from the base station. Specifically, the first measurement gap may be obtained from the base station side when the cooperative UE determines that the measurement capability of the cooperative UE is that the measurement gap is not needed to perform inter-frequency/inter-system measurement.
The configuration information of the measurement gap may be: measurement of the Gap offset (gapOffset), Measurement of the Gap length (MGL), Measurement of the Gap Repetition Period (MGRP), Measurement of the Gap Advance (MGTA), and the like.
The cooperation information may also include measurement capability of the cooperating UE, and the measurement capability may specifically be: whether the UE needs to measure the gap when performing inter-frequency/inter-system measurement, for example, the UE needs to measure the gap when performing inter-frequency/inter-system measurement, or the UE does not need to measure the gap when performing inter-frequency/inter-system measurement. The inter-frequency measurement can be understood as that the current serving cell and the target cell of the UE are not on the same carrier frequency point; the inter-system measurement may be understood as that the target cell and the current serving cell belong to different communication systems, such as a 4G system and a 5G system. The target cell may be a cell adjacent to the current serving cell of the UE.
S202, the cooperative UE sends the cooperative information to a source UE, and the cooperative information is used for indicating the source UE to carry out cooperative transmission.
The cooperation information may indicate the source UE to perform cooperation transmission, and specifically, may indicate the source UE to perform cooperation transmission during the first measurement gap.
When the capability of the cooperative UE is that the pilot frequency/inter-system measurement is performed without the need of the measurement gap, the first measurement gap is obtained from the base station, and the source UE is indicated to perform cooperative transmission during the first measurement gap according to the first measurement gap, so that when the cooperative UE performs the cooperative transmission, the base station does not schedule the cooperative UE, the cooperative transmission performed by the cooperative UE does not conflict with the scheduling of the base station, and the stability and reliability during the cooperative transmission are improved.
S203, the source UE receives the cooperation information sent by the cooperative UE.
And S204, the source UE performs cooperative transmission with the cooperative UE according to the cooperative information.
If the cooperation information is the first measurement gap, the source UE and the cooperation UE carry out cooperation transmission during the first measurement gap; if the cooperative information is the measurement capability of the cooperative UE, when the measurement capability is that the cooperative UE does not perform inter-frequency/inter-system measurement through the measurement gap, the configuration information of the second measurement gap of the source UE may be sent to the cooperative UE to indicate the cooperative UE to perform non-cooperative transmission during the second measurement gap. The source UE and the cooperating UE may perform cooperative transmission at a time other than the second measurement gap period.
In one possible implementation, when the cooperation information is the measurement capability of the cooperating UE, the source UE may further perform the following method:
a1, if the measurement capability of the cooperative UE is that the measurement gap is not needed to perform inter-frequency/inter-system measurement, and the measurement capability of the source UE is that the measurement gap is needed to perform inter-frequency/inter-system measurement, the source UE acquires configuration information of a second measurement gap;
a2, the source UE sending configuration information of the second measurement gap to the cooperative UE to instruct the cooperative UE to perform non-cooperative service during the second measurement gap.
The method for the source UE to obtain the configuration information of the second measurement gap may be: and reporting the measurement event A2 to the base station, and receiving the measurement gap configured by the base station to obtain a second measurement gap.
The non-cooperative service may include not transmitting data to the source UE, or performing a self-service, etc.
In this example, when the measurement capability of the cooperative UE is that the measurement gap is not needed to perform inter-frequency/inter-system measurement, and the measurement capability of the source UE is that the measurement gap is needed to perform inter-frequency/inter-system measurement, the second measurement gap is sent to the cooperative UE to indicate the cooperative UE to execute the non-cooperative service during the second measurement gap, so that the problem that when the source UE executes measurement, the cooperative UE sends data to the source UE and cannot receive the data, which causes resource waste can be avoided, thereby saving system overhead and reducing resource usage.
In a possible implementation manner, the cooperative UE may further obtain configuration information of the first measurement gap, and a possible method for obtaining the configuration information of the first measurement gap includes:
b1, if the measurement capability of the cooperative UE is that the measurement gap is not needed to be measured for inter-frequency/inter-system measurement, the cooperative UE reports the gap to be measured to the base station;
b2, if the cooperative UE determines not to execute pilot frequency/inter-system measurement, reporting a measurement event to a base station;
b3, the cooperative UE receives the configuration information of the first measurement gap sent by the base station.
The method for the cooperative UE to determine whether the measurement capability is the inter-frequency/inter-system measurement without measuring the gap may be: and determining whether the measurement capability is the different frequency/different system measurement without the need of measuring the gap according to the hardware information.
In this example, when it is determined that the measurement capability does not require the measurement gap to perform inter-frequency/inter-system measurement, the configuration information of the first measurement gap is obtained by the base station, so that the cooperative UE and the source UE can perform cooperative transmission during the first measurement gap, and when the cooperative UE performs cooperative transmission, the base station does not schedule the cooperative UE, so that the cooperative transmission performed by the cooperative UE does not conflict with the scheduling of the base station, and stability and reliability during cooperative transmission are improved.
In a possible implementation manner, the cooperative UE may further receive a measurement gap sent by the source UE, and perform non-cooperative service during the measurement gap, which specifically includes:
c1, the cooperative UE receiving configuration information of a second measurement gap sent by the source UE, where the configuration information of the second measurement gap is acquired when the measurement capability of the source UE is that the measurement gap is not needed to perform inter-frequency/inter-system measurement, and the measurement capability of the source UE is that the measurement gap is needed to perform inter-frequency/inter-system measurement;
c2, the cooperative UE executing non-cooperative service during the second measurement gap according to the configuration information of the second measurement gap.
And executing the non-cooperative service during the second measurement gap, so that the cooperative service and the non-cooperative service do not conflict, and the reliability of cooperative transmission is improved.
Referring to fig. 3, fig. 3 is an interaction diagram of another cooperative transmission method according to an embodiment of the present application. As shown in fig. 3, the cooperative transmission method includes:
s301, the cooperative UE judges whether the measurement capability is the gap needing to be measured, and if the measurement capability is judged not to be the gap needing to be measured, the cooperative UE reports the gap needing to be measured to the base station.
The method for the cooperative UE to determine whether the measurement capability is the gap to be measured may be that the cooperative UE determines whether the measurement capability needs to measure the gap according to its own hardware capability, for example, frequency band information supported by a radio frequency channel.
S302, the cooperative UE judges whether the pilot frequency/different system measurement needs to be executed or not, and reports a measurement event to the base station if the pilot frequency/different system measurement does not need to be executed.
Whether the measurement capability does not need to perform inter-frequency/inter-system measurement may be determined according to the environment, for example, when the cooperative UE is in a stationary or low-speed moving state or in a cell center, the channel quality is good, and the inter-frequency/inter-system measurement may not be performed. The measurement event may be measurement event a2, and after receiving the measurement event sent by the cooperative UE, the base station configures a measurement gap, that is, a first measurement gap.
S303, the cooperative UE receives the first measurement gap sent by the base station.
S304, the cooperative UE sends the first measurement gap to the source UE.
S305, the source UE performs cooperative transmission with the cooperative UE during the first measurement gap.
In this example, when it is determined that the measurement capability does not require the measurement gap to perform inter-frequency/inter-system measurement, the configuration information of the first measurement gap is obtained by the base station, so that the cooperative UE and the source UE can perform cooperative transmission during the first measurement gap, and when the cooperative UE performs cooperative transmission, the base station does not schedule the cooperative UE, so that the cooperative transmission performed by the cooperative UE does not conflict with the scheduling of the base station, and stability and reliability during cooperative transmission are improved.
