Description

In-band relay method, relay equipment and network equipment

Technical Field

The present application relates to the field of mobile communications, and in particular, to an in-band relay method, a relay device, and a network device.

Background

A Relay networking defined by the third generation partnership project (3 GPP) standard includes two logical nodes, a donor base station (donor eNodeB, DeNB for short) and a Relay device Relay. The DeNB is a base station (eNodeB, eNB) that has added support for related functions of relay characteristics, and when accessing a general User Equipment (UE), the DeNB also supports access to the relay and carries backhaul traffic of the relay. The relay is logically divided into two parts, namely Relay User Equipment (RUE) and a relay base station (ReNB): the ReNB can be accessed by common UE in a coverage range, and establishes an access link with the common UE; the RUE accesses the DeNB and establishes an air interface bearer to provide a backhaul link for the RUE. If the return link and the access link of the relay use the same frequency band, the relay is called an in-band relay; if the backhaul link and the access link of the relay use different frequency bands, they are called out-of-band relay.

The total frequency spectrum occupied by the return link and the access link of the in-band relay is smaller than that occupied by the out-of-band relay, namely, the frequency spectrum efficiency is higher than that of the in-band relay. But an in-band relay needs to solve the interference problem between the backhaul link and the access link. The 3GPP standard defines a Time Division Multiplexing (TDM) approach to avoid interference between the in-band relay backhaul link and the access link. Specifically, in the downstream direction, only one of the following two actions occurs at the same time: the RUE receives data of the DeNB, and the ReNB sends data to the common UE below the RUE; in the uplink direction, only one of the following two actions occurs at the same time: the RUE sends data to the DeNB, and the ReNB receives data of the common UE.

In the prior art, a DeNB avoids mutual interference between an inband relay backhaul link and an access link through configuration of a relay subframe, specifically, the DeNB issues to an RUE through a cell subframe configuration fdd, and the configuration of the cell subframe configuration fdd is as follows in table 1:

TABLE 1

SubframeConfigurationFDD	ΔBSC
		{xxxxxxx1}	7
{xxxxxx1x}	6
		{xxxxx1xx}	5
{xxxx1xxx}	4
		{xxx1xxxx}	3
{xx1xxxxx}	2
		{x1xxxxxx}	1
{1xxxxxxx}	0

Wherein, each cell subframe configuration FDD corresponds to a delta BSC, and the delta BSC value satisfies the following formula (10 × n)_f+[n_s/2]) mod8 ∈ Δ BSC, e.g., Δ BSC equals 7, n_fAnd n_sThe 40ms subframes corresponding to the values of (0, 14), (1, 10), (2, 6) and (3, 2) are respectively 7, 15, 23 and 31 subframes, and since the system message is transmitted in 0, 4,5 and 9 subframes, the 15 subframes cannot be configured, that is, when Δ BSC equals 7, the configuration subframes are 7, 23 and 31. Similarly, when the cell subframe configuration fdd is otherwise, each cell subframe configuration fdd corresponds to 3 subframes, and is configured in units of at least 3 subframes within 40ms, and therefore, the periodic CQI resources and the SRI resources of the users in the ReNB cannot be accurately controlled.

In this embodiment of the present application, after receiving one first subframe, which is sent by a network device and allocated according to a first subframe set, a relay device may configure an uplink control channel resource according to the received one first subframe. Specifically, the relay device may use the received first subframe as an uplink control channel resource occupied in a scheduling period.

In an embodiment, the relay ue configures an uplink control channel resource according to the received first subframe.

303. The relay device allocates a second subframe to a first terminal device according to a second subframe set, wherein the second subframe belongs to the second subframe set, the second subframe set includes at least one second subframe, each second subframe in the at least one second subframe is different from another second subframe, each second subframe is used for indicating an uplink control channel resource occupied by a second link in a scheduling period, the second link is a link between the relay device and a first terminal device accessing the relay device, and an intersection of the first subframe set and the second subframe set is an empty set.

In the embodiment of the application, the first terminal device is a terminal device directly connected with the relay device.

Specifically, the relay device may allocate a second subframe to the first terminal device according to a second subframe set, where the second subframe belongs to the second subframe set, the second subframe set includes at least one second subframe, each of the at least one second subframe is different from another one, each of the at least one second subframe is used to indicate an uplink control channel resource occupied by a second link in a scheduling period, the second link is a link between the relay device and the first terminal device accessing the relay device, and an intersection of the first subframe set and the second subframe set is an empty set.

Taking an example of a scheduling period being 10ms, in this case, one scheduling period may correspond to 10 subframes {0,1,2,3,4,5,6,7,8,9}, a first subframe set may include at least one of the 10 subframes, and a second subframe set includes at least one of the 10 subframes, and an intersection of the first subframe set and the second subframe set is an empty set, that is, the first subframe set and the second subframe set do not include the same subframe, for example, the first subframe set may include only one subframe: 0, the first set of subframes is {0}, and the second set of subframes does not include 0, e.g., the second set of subframes may be {1,3,5,7,9}, and thus the intersection of the first set of subframes {0} and the second set of subframes {1,3,5,7,9} is an empty set. For example, the first set of subframes may include only 5 subframes: 0,2,4,6,8, the first subframe set is {0,2,4,6,8}, in which case the second subframe set does not include 0,2,4,6,8, e.g., the second subframe set may be {1,3,5,7,9}, and it can be seen that the intersection of the first subframe set {0,2,4,6,8} and the second subframe set {1,3,5,7,9} is an empty set.

It should be noted that, in the second subframe set, each second subframe in at least one second subframe is different, which is different from the first subframe set in another expression, the second subframe set does not include repeated second subframes.

In one embodiment, the relay base station transmits the one second subframe to the first terminal device.

In this embodiment, because the network device selects one subframe from the first subframe set to allocate to the relay device, and the relay device selects one second subframe from the second subframe set to allocate to the terminal device, because the intersection of the first subframe set and the second subframe set is an empty set, that is, the first subframe set and the second subframe set do not include the same subframe, the subframe allocated to the relay device by the network device is different from the subframe allocated to the terminal device by the relay device, uplink control channel interference that the RUE may block the terminal device accessing the ReNB is eliminated, and uplink control channel interference that the terminal device accessing the ReNB may block the RUE is eliminated. On the other hand, since the relay device may select one second subframe from the second subframe set to allocate to the terminal device, compared with the existing standard, the relay device may only be configured in units of 3 subframes at least, and in this embodiment, the relay device may be configured in units of at least 1 subframe, and further, may implement accurate control on periodic CQI resources and SRI resources of users under the ReNB.

In this embodiment, the first subframe set corresponds to a relay device, the second subframe set corresponds to a first terminal device directly connected to the relay device, the third subframe set corresponds to a second terminal device directly connected to a network device, and the fourth subframe set is all subframes occupied by one scheduling period. And the intersection of any two subframe sets in the first subframe set, the second subframe set and the third subframe set is an empty set, and in another expression mode, the intersection of the first subframe set and the second subframe set is an empty set, the intersection of the first subframe set and the third subframe set is an empty set, and the intersection of the second subframe set and the third subframe set is an empty set. In addition, the union of the first subframe set, the first subframe set and the third subframe set is a fourth subframe set.

Taking an example of a scheduling period of 10ms, in this case, the fourth subframe set is {0,1,2,3,4,5,6,7,8,9}, and illustratively, the first subframe set is {0}, the second subframe set is {1,3,5,7,9}, the third subframe set is {2, 4,6,8}, it can be seen that an intersection of any two subframe sets in the first subframe set {0}, the second subframe set {1,3,5,7,9} and the third subframe set {2, 4,6,8} is an empty set, and a union of the first subframe set {0}, the second subframe set {1,3,5,7,9} and the third subframe set {2, 4,6,8} is the fourth subframe set {0,1,2,3,4,5,6,7,8,9 }.

Illustratively, the first set of subframes is {0,2, 4}, the second set of subframes is {1,3,5,7,9}, the third set of subframes is {6, 8}, it can be seen that an intersection of any two of the first set of subframes {0,2, 4}, the second set of subframes {1,3,5,7,9} and the third set of subframes {6, 8} is an empty set, and a union of the first set of subframes {0,2, 4}, the second set of subframes {1,3,5,7,9} and the third set of subframes {6, 8} is a fourth set of subframes {0,1,2,3,4,5,6,7,8,9 }.

It should be noted that, in practical application, the above is only two examples of the first subframe set, the second subframe set and the third subframe set, and may be selected as required as long as the fourth subframe set includes all subframes occupied by one scheduling cycle, an intersection of any two subframe sets of the first subframe set, the second subframe set and the third subframe set is an empty set, and a union of the first subframe set, the second subframe set and the third subframe set is the fourth subframe set, which is not limited in the embodiment of the present application.

Through the above manner, since the network device selects one subframe from the first subframe set to allocate to the relay device, and the relay device selects one second subframe from the second subframe set to allocate to the terminal device, since the intersection of the first subframe set and the second subframe set is an empty set, that is, the first subframe set and the second subframe set do not include the same subframe, the subframe allocated to the relay device by the network device is different from the subframe allocated to the terminal device by the relay device, uplink control channel interference on the terminal device accessing the ReNB due to the RUE is eliminated, and uplink control channel interference on the RUE due to the terminal device accessing the ReNB is eliminated. On the other hand, since the relay device may select one second subframe from the second subframe set to allocate to the terminal device, compared with the existing standard, the relay device may only be configured in units of 3 subframes at least, and in this embodiment, the relay device may be configured in units of at least 1 subframe, and further, may implement accurate control on periodic CQI resources and SRI resources of users under the ReNB.

Taking an example of a scheduling period being 10ms, in this case, one scheduling period may correspond to 10 subframes {0,1,2,3,4,5,6,7,8,9}, the first subframe set may include at least one of the 10 subframes, and the third subframe set includes at least one of the 10 subframes, and an intersection of the first subframe set and the third subframe set is an empty set, that is, the first subframe set and the third subframe set do not include the same subframe, for example, the first subframe set may include only one subframe: 0, the first set of subframes is {0}, and the third set of subframes does not include 0, e.g., the third set of subframes may be {1,3,5,7,9}, and thus the intersection of the first set of subframes {0} and the third set of subframes {1,3,5,7,9} is an empty set. For example, the first set of subframes may include only 5 subframes: 0,2,4,6,8, the first subframe set is {0,2,4,6,8}, in which case the third subframe set does not include 0,2,4,6,8, e.g., the third subframe set may be {1,3,5,7,9}, and it can be seen that the intersection of the first subframe set {0,2,4,6,8} and the third subframe set {1,3,5,7,9} is an empty set.
