Description

Signal transmitting method and device for soft switching area of unbalanced area of heterogeneous network

Technical field

The present invention relates to the field of communications technologies, and in particular, to a signal transmission method and apparatus for a soft handover area of an unbalanced area of a heterogeneous network. Background technique

In order to enhance the processing capability of the network, the prior art provides a heterogeneous network (Hetnet, Heterogeneous Network) technology. Heterogeneous networks typically include a macro base station and a base station. If the transmit signal of the user equipment (User Equipment, UE) located in the heterogeneous network has the same signal strength at the macro base station and the micro base station, the location of the user equipment in the heterogeneous network is referred to as an uplink balance point. If the signals transmitted by the macro base station and the micro base station have the same signal strength at the user equipment, the location of the user equipment in the heterogeneous network is referred to as the downlink balance point. The area between the upstream balance point and the downstream balance point is called an unbalanced area.

When the user equipment is in the soft handover area of the unbalanced area, the inventors have found that the prior art has the following problems: When the macro base station does not receive the uplink service request information, the uplink service is unstable; when the macro base station does not receive the downlink data, When the information is feedback, the downlink service is unstable. At the same time, because the first power control command sent by the micro base station is not stably received at the user equipment in the handover area where the user equipment is located, the micro base station cannot effectively suppress the transmission power of the user equipment, and brings uplink interference to the micro base station. .

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, those of ordinary skill in the art do not make All other embodiments obtained under the premise of creative labor are within the scope of the invention. The application scenario provided by the example of the present invention is applicable to a soft handover area in an unbalanced area of a heterogeneous network. Optionally, in the soft handover area, the micro base station is an uplink primary serving base station, and the macro base station is a downlink primary serving base station. Alternatively, in the soft handover area, the micro base station is an uplink secondary serving base station, and the macro base station is a downlink primary serving base station.

The embodiment of the present invention provides a signal transmitting apparatus for a soft handover area of an unbalanced area of a heterogeneous network, and the apparatus may be a micro base station. As shown in FIG. 1, the apparatus includes: a first receiving unit 101, a comparing unit 102, and a sending Unit 103.

The first receiving unit 101 is configured to receive a signal sent by the user equipment in the unbalanced area. In this step, the signal sent by the user equipment is a data signal and/or a control signal. When the signal is a data signal, the data signal is carried on an Enhanced Dedicated Physical Channel (E-DPDCH); when the signal is a control signal, The control signal is carried on a dedicated physical control channel (Dedicated Physica Control Channe l, DPCCH).

The obtaining unit 102 is configured to acquire a first power control command according to the received power of the signal received by the first receiving unit 101.

Further, when the signal sent by the user equipment received by the first receiving unit 101 includes a data signal and/or a control signal, the first power control command may be acquired according to the received power of the data signal and/or the control signal. For example: According to the sum of the received power of the data signal and the control signal, the first power control command is obtained, and the first power control command may also be acquired according to the received power of the data signal or the control signal. Optionally, the received power of the data signal and/or the control signal may further include pilot power or other quantity calculated by power, such as a signal to interference ratio, and therefore, a received power of the data signal and/or the control signal. It can be a data signal to signal ratio or a control signal to interference ratio.

The sending unit 103 is configured to send the first power control command acquired by the acquiring unit 102 to the user equipment.

For the embodiment of the present invention, by transmitting the first power control command to the user equipment, the user equipment may be configured to adjust the transmission power of the signal of the user equipment according to the first power control command. According to The adjusting, by the first power control command, the transmit power of the signal of the user equipment comprises adjusting a signal transmit power configured by the user equipment. Specifically, the transmit power of the data signal of the user equipment or the transmit power of the control signal is adjusted according to the first power control command. The adjustment of the data signal transmission power can be achieved by adjusting the E-DPDCH/DPCCH ratio or by referring to the E-DPDCH/DPCCH ratio.

In this step, the first power control command is carried on the split dedicated physical channel (Frac ti ona l-Dedi ted Phys i ca l Channe l , F-DPCH ), that is, the transmitting unit 103 passes the F-DPCH to be the first The power control command is sent to the user equipment.

Optionally, the bearer mode of the first power control command may be: pre-defining X symbol sequences of length N times slot units. Where N is the sequence period and X sequences are respectively X different transmit power configurations. The UE first receives the sequence of symbols, then obtains a transmit power indication value for the sequence, and finally configures a new transmit power transmit signal by the indicated value.

Specifically, the signal can be carried by an offset relative to the current transmit power. For example, if the UE's transmit power at the current time is f (PO) (dB), when the UE receives the first symbol sequence, the obtained first symbol sequence indicator value is a, then the UE follows f (PO+). a) (dB) to configure the transmit signal power; when the UE receives the second symbol sequence, the obtained second symbol sequence indicator value is b, then the UE follows f (PO+a+b) (dB) Configure the transmit signal power.

In particular, the signal can also be carried by an offset relative to some fixed transmit power. For example, if the preset fixed transmit power of the UE is f (PO) (dB), when the UE receives the first symbol sequence, the obtained first symbol sequence indicator value is a, and the UE follows f (PO+). a) (dB) to configure the transmit signal power; when the UE receives the second symbol sequence, the obtained second symbol sequence indicator value is b, then the UE configures the transmission according to f (PO+b) (dB) Signal power.

Specifically, the signal can also be carried by direct indication. For example, if the UE's transmit power at the current time is f (PO) (dB), when the UE receives the first symbol sequence, the obtained first symbol sequence indicator value is a, then the UE follows f (a).
